Best Digital Multimeter 2026: 10 Ranked, and the Number That Doesn't Measure Anything
By Felipe Iglesias · Updated
The biggest number in this category is not a measurement. The £11.99 AstroAI carries 55,860 ratings — more than the next two digital multimeter listings combined (22,442 + 19,497 = 41,939) — yet it is a 2000-count meter that reads DC current but not AC current, and has no capacitance, frequency or temperature range. The star ratings barely separate the rest: every meter here sits between 4.4 and 4.7. What actually tells them apart are the specs the listings contradict.
We ranked ten of the best digital multimeter options sold on Amazon on three honest criteria: what the meter physically measures, how its safety rating is stated, and how often the listing's own numbers disagree with one another.

KAIWEETS HT118A 6000-Count True RMS Multimeter
Top of the list because it is the only meter claiming both CAT III 1000V and CAT IV 600V, and it reads AC current as well as DC at 6000 counts.
Pros
- CAT III 1000V and CAT IV 600V — the highest pair of voltage categories in this roundup
- 6000-count resolution with true RMS across AC and DC
- Reads AC current as well as DC, which the £11.99 meter here cannot do
- 2.9in backlit LCD with dual display, bar graph, LED jack lighting and a rear torch
- 36-month after-sale service and lifetime technical support from KAIWEETS
Cons
- £39.99 is the highest price in the roundup
- 550g and 20.4 x 13 x 6.2cm make it the bulkiest of the ten
- Its own sheet lists an upper temperature rating of 250°C, below cheaper rivals' claims
- 22,442 ratings at 4.6 sit behind the £11.99 meter's 55,860
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Looked at the review on the YouTube Dronebot Workshop comparing a range of multimeters and this one was right up there. Feels premium quality. I noticed that a number of Amazon reviews stated there was no continuity buzzer, however if you press the function button this toggles the feature. All in all, happy with my purchase.”
Verified purchase“Works as intended.Seems accurate so far.Quite a beefy unit but still portable enough to carry around.Very solidly built - this is going to last a long time.Clear display and has all the functions you would expect/need.Excellent.”
At £39.99 this is the most expensive meter in the line-up, and the only one claiming both CAT III 1000V and CAT IV 600V. Crucially, it also reads AC current as well as DC — something the £11.99 meter at the bottom of this list cannot do. A digital multimeter without AC current is fine for batteries and continuity, and not much else.
The 6000-count resolution, 2.9in backlit LCD, dual display with bar graph and the LED lights that show which jack to use are all built for speed. It measures AC/DC voltage, AC/DC current, resistance, continuity, frequency, capacitance, duty cycle, diodes and temperature, with non-contact voltage detection and a live-wire mode that turns the screen red. It weighs 550g and measures 20.4 x 13 x 6.2cm, so it lives in a toolbox rather than a pocket. KAIWEETS offers 36 months of after-sale service and lifetime technical support.
That said, the same sheet lists an upper temperature rating of 250°C, below the figures printed on cheaper listings here. Anyone who mainly checks batteries, sockets and fuses is paying for ranges they will never use. Buy this if you want the highest safety category and every range on one dial; skip it if you want something light.
AstroAI TRMS 6000-Count Multimeter, CAT III 600V
Second because £21.92 buys true RMS, AC/DC current, capacitance, frequency, duty cycle and temperature, with 19,497 ratings behind it.
Pros
- £21.92 for 6000 counts, true RMS, AC/DC current, capacitance, frequency, duty cycle and temperature
- 19,497 ratings at 4.6 — the second-largest sample in the roundup
- Two ceramic fuses rated F400mA/600V and F10A/600V
- Data hold, backlit LCD, kickstand and auto shut-off included
Cons
- The title says CAT III 600V while the specification table gives a maximum operating voltage of 1000V
- Its own sheet lists a lower temperature rating of 40°C and an upper of 1370°C
- 492g is the second-heaviest meter here
- No carrying case listed among the included components
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“An excellent, sturdy multimeter at a very good price. I bought it as a cheap temporary replacement when my professional electronics meter gave problems and I was in a hurry to get something simple for DC voltage. On receipt I was pleasantly surprised by how well the extensive options work. As regards accuracy it meets it's specifications, at least for Voltage, Resistance, Capacitance and Temperature. I see that some other reviewers only give it four stars because of accuracy stating they would prefer something more expensive. To my my mind that is just being perverse and a bit like comparing a Ford Fiesta to an Aston Martin DB12. My very accurate professional meter cost over £650 so I am delighted with the performance of the AstroAI for less than £22.”
Verified purchase“This is a good value for money multimeter with features usually only available on more expensive brands.I ordered it as an emergency while on holiday as I had forgotten my other one. It was refreshing to have a clear set of instructions with it.This is now my go-to multimeter”
Meanwhile, £21.92 buys 6000 counts, true RMS, AC/DC current, capacitance, frequency, duty cycle and temperature, plus 19,497 ratings at 4.6 — the second-largest review base here. On paper that is the widest function list per pound in the top half of the ten.
In practice the extras are the ones that matter at the consumer unit: data hold, a backlit LCD, a kickstand and auto shut-off, plus two ceramic fuses rated F400mA/600V and F10A/600V. The 9V battery, test leads and a multi-function socket are in the box, and the support team is US-based and quotes a 24-hour reply. It weighs 492g, the second-heaviest here.
The catch is that its own specification contradicts its title. The name says CAT III 600V; the sheet gives a maximum operating voltage of 1000V. The same sheet lists a lower temperature rating of 40°C and an upper of 1370°C. As with every digital multimeter listing here, read the table rather than the headline.
AstroAI TRMS 4000-Count Multimeter, Auto or Manual Range
Third on value: £17.99 for true RMS, auto-ranging, AC/DC current and temperature coverage in a 145g body, at 4000 counts instead of 6000.
Pros
- £17.99 for true RMS with both auto and manual ranging
- 4000 counts covering AC/DC voltage, AC/DC current, resistance, continuity, capacitance, frequency and temperature
- 145g and 15.5 x 10.8 x 3.9cm — light enough to keep in a bag
- F500mA/600V and F10A/600V fuses, overload protection on all ranges, three-year warranty
Cons
- Its upper temperature rating is listed as 40°C on a meter being sold for temperature measurement
- 4000 counts against 6000 on the two meters above it
- The included components field simply reads '1' — no detail on what arrives
- 8,850 ratings is less than a sixth of the £11.99 meter's count
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I have many years under my belt as an electronics engineer diagnosing component level faults on pcb's and I am used to much more expensive DVM's (digital voltmeters) so I feel qualified to review this one.First off the price is really cheap so I wasn't expecting much but I was pleasantly surprised that is wasn't as bad as I was expecting it to be.It's quite light in the hand but feels well made, mostly hard plastic with a hard rubberised outer case which should negate some drops and bangs.The bale stand on the back is flimsy and will probly break if flexed the wrong way too much so just be gentle with it and it should be okay.The screw which holds the battery cover / stand on goes in to a brass insert and not just screwed in to plastic so thats nice.The screen is easy to read at different angles and has nice large numbers on and while isn't the quickest at updating its okay considering the price.The test leads are fine and work okay for general useI cant comment on battery life as I have not had it long, this review is first impressions.I have attached some pictures where I tested the accuracy of this DVM, the DMM Check Plus was Calibrated recently and I checked it with one of my Flukes just before testing the AstroAI DT132A and the Fluke read spot on for each of the tests.The tests performed were AC & DV volts , AC & DC mA and Resistance, you can see the results for yourself.”
Verified purchase“Basic and solid multimeter at a good price. Very good for someone who is venturing into electronics for the first time.”
Third at £17.99, and the value pick of the three AstroAI meters here. It claims the same true RMS, the same auto-ranging and the same AC/DC current and temperature coverage as the £21.92 model above, in a 145g body.
The headline difference is resolution: 4000 counts against 6000. It still covers AC/DC voltage, AC/DC current, resistance, continuity, capacitance, frequency, temperature and diodes, with data hold, a backlit LCD, a kickstand and a low-battery indicator. Two fuses rated F500mA/600V and F10A/600V, overload protection on all ranges, CE, RoHS and UL marks, and a three-year warranty from AstroAI. It measures 15.5 x 10.8 x 3.9cm.
By contrast with the marketing, the bullets promise temperature measurement while the specification gives an upper temperature rating of 40°C. That is the clearest contradiction in the category. It also carries the fewest reviews of the three AstroAI models — 8,850 against 55,860 for the cheap one. Skip it if you need 6000-count resolution.
TESMEN TM-510 Smart 4000-Count Voltage Tester
Fourth because 13,613 ratings at 4.6 and a £16.99 price make it the popular choice for voltage-only work, and it measures no current at all.
Pros
- 13,613 ratings at 4.6 — the third-largest review base in the roundup
- £16.99, 100g, two AAA batteries, storage bag and manual supplied
- Smart Auto Mode needs no mode or range selection from the user
- Non-contact voltage detection with both audible and visual alarm
Cons
- CAT II 600V is the lowest safety category here
- No current, capacitance, frequency or temperature measurement listed
- 4000 counts against 6000 on the three meters above it
- The compatible devices field says only 'Test Leads' — no device list is given
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“So simple to use, no more having to use a dial to select the right type of electricity, high voltage mains or a small 3v battery, it just knows. The 'live' detector works well. It won't detect buried wires in a wall, but it will tell you if a light switch, plug socket or flex is live. Ideal for the general handyman and DIY'er”
Verified purchase“Great quality, clear instructions. The 'find the hidden mains cable' is extremely useful. Wonderfully versatile and has a readable manual in English!! Excellent value for money and highly recommended.”
Fourth, and the meter most people will recognise: 13,613 ratings at 4.6, the third-largest base here, at £16.99. It is also the lightest of the ten, at 100g, and runs on two AAA batteries.
The idea is simplicity. Smart Auto Mode switches between AC/DC voltage, resistance and continuity with no dial work, and non-contact voltage detection gives an audible and visual alarm without touching a conductor. Data hold, automatic shutdown, a backlit screen, a torch, a storage bag and a user manual are all included. Safety is stated as CAT II 600V with CE and RoHS.
That said, the function list stops at voltage, resistance and continuity — no current, no capacitance, no frequency and no temperature. For a multimeter for home electrical testing around sockets, switches and fuses, that is enough. If you need to measure current, or you work near the consumer unit, note that CAT II is the lowest safety category here and you should look further up the list. Its 4000 counts are also below the three meters above it.
Neoteck 2000-Count Multimeter with NCV and Temperature
Fifth for features rather than resolution: £19.99 covers capacitance, frequency, temperature and NCV, but the display is only 2000 counts.
Pros
- £19.99 covers capacitance, frequency, duty cycle, temperature, live wire and NCV
- Temperature probe and 10A alligator clip included in the box
- Manual and automatic range switching, data hold, 15-minute auto shut-off, torch
- CAT III 600V with overload and short-circuit protection; 195g
Cons
- 2000 counts — the same resolution as the £11.99 meter, at £8 more
- Costs more than the 4000-count AstroAI at £17.99
- Its 1000°C upper temperature rating cannot be compared with the 250°C and 40°C figures on rival listings
- 1,761 ratings is one of the smaller samples here
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I am replacing a Precision Gold Academy PG017 and it uses the identical probe sizes. Auto ranging to 2000 units with fixed range option. With zip and loop, nylon padded holder bag, Elastic protective cover. Accessories, probes, crocodile extensions, thermo-couple thermometer, no spare fuses. Torch lamp. Non-contact voltage detector, diode test, hold display, Multilingual manual, Frequency and capacitance measurement. Auto-sleep”
Verified purchase“An excellent,reasonably priced multi-meter for use around the home and car. Easy to use but I would recommend reading the manual to get the best from it. It does everything I'm ever likely to need and more besides. The included case keeps everything together and it even came with batteries which was a pleasant surprise at this price point. I particularly like that it has a Non-Contact Voltage function so I don't drill into live cables. It's more than accurate enough for a DIY user like me. Pleased I bought it.”
Fifth because of a price that does not match its resolution. At £19.99 this is a 2000-count meter — the same count as the £11.99 model at the bottom — and it costs more than the £17.99 AstroAI above it.
What you do get is range: DC and AC voltage and current, resistance, capacitance, frequency, duty cycle, continuity, diode, temperature, live wire and NCV, with DC voltage accuracy stated at ±0.5%. It switches between manual and automatic ranging, holds data, shuts down after 15 minutes idle and carries a torch. CAT III 600V, CE and RoHS, with overload and short-circuit protection. The box includes a temperature probe and a 10A alligator clip. It weighs 195g and measures 14 x 7.2 x 3.7cm.
Worth noting: its upper temperature rating is listed as 1000°C. The £11.99 meter says 250°C; the £17.99 AstroAI says 40°C. Three meters, three numbers for the same field, which is exactly why none of them can be compared directly. For a multimeter for beginners the function list is generous, but 2000 counts is still 2000 counts.
Proster 6000-Count Manual-Range Multimeter, T28C
Sixth because its own highlight calls it auto-ranging while its bullets and style name say manual range — you pick the interval yourself.
Pros
- 6000 counts with 750V AC, 1000V DC and 20A AC/DC current
- Manual range selection on every function, which suits repeatable bench work
- Two spare fuses in the battery compartment plus two spare fuse access points
- Magnetic back, fold-out stand, alligator clips, temperature probe, screwdrivers and cloth bag; 18-month warranty
Cons
- The item highlight calls it auto-ranging while the bullets and style name say manual range
- £27.98 costs more than both 4000 and 6000-count AstroAI meters above it
- No data hold or auto power-off mentioned in the bullet points
- 1,750 ratings at 4.6 is one of the smaller samples here
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“For the price, this is an excellent multimeter with plenty of features for DIY and home electrical work. The auto-ranging function makes it easy to use, and the display is clear with a helpful backlight for working in darker areas. The included temperature probe and NCV function are useful extras, and the unit feels solid and well made. Accurate, reliable, and great value for money. Highly recommended for both beginners and experienced users !!”
Verified purchase“Arrived on time and well packaged. One small problem though, the item comes with four AAA batteries, two were fully charged, and two had no voltage in them. Fortunately I have plenty of these batteries.”
Sixth, and the clearest case of a listing arguing with itself. The item highlight calls it an auto ranging multimeter; the second bullet and the style name, '6000Counts 20A-Manual Range', describe manual range selection. Both cannot be right, so check before you buy.
The rest of the spec is solid for the money: 6000 counts, 750V AC and 1000V DC, 20A AC/DC current, resistance, capacitance, frequency, duty cycle, temperature, continuity, NCV, diode, hFE and an infrared test. Two spare fuses sit in the battery compartment, with two spare fuse access points. A magnetic back, fold-out stand, alligator clips, temperature probe, screwdrivers and a cloth bag are included, and Proster gives 18 months of warranty. It weighs 380g.
The catch is that manual ranging means you select the measurement interval yourself for every reading — accurate and repeatable, slower in a hurry. At £27.98 it costs more than both AstroAI meters above it, and its 1,750 ratings are among the smallest samples in the roundup. Skip it if you want point-and-read. If you want an electrical tester that behaves identically every time on a bench, this is the one.
Crenova 890Z 6000-Count TRMS Multimeter
Seventh on the highest rating here, 4.7 from 664 ratings, with a fuller accessory kit than anything else in the top half.
Pros
- 6000 counts with AC/DC current, capacitance, frequency, hFE and temperature
- Full kit: K-type thermocouple, probe leads, alligator clip leads, two AA batteries, carrying box and manual
- CAT III rated with double fuse protection, silicone cover and low-battery indication
- 4.7 stars — joint-highest here — from 664 ratings
Cons
- 820g makes it the heaviest meter in the roundup
- 664 ratings gives the 4.7 a far thinner base than 22,442 ratings at 4.6
- No IP rating and no CAT IV claim, unlike the £23.02 Amazon Basics
- £33.97 is the second-highest price here
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Unboxing : The product is packed in a strong cardboard outer box. Inside the box is a hardshell carry case, which contains the product. The meter itself is packaged in bubblewrap to protect while in transit.Hardshell carry case : The hardshell case is a real bonus as these are quite expensive to purchase separately and this carry case is custom made for this product, so the fit is perfect with plenty of room for all the accessories. The case opens with a strong zipper and then unfolds into two halves with a net-covered pocket in the left half and an elasticated strap in the right half. These do a good job of holding the meter and the other components.Contents : Inside the carry case is the meter; two sets of test leads (one with crocodile clips); a temperature test lead; 2 x AA batteries; 2 x fuses and an instruction manual that is written in good English. The instruction manual is also available as a downloadable PDF file.Preparation : The batteries have to be fitted. To fit the batteries the battery cover needs to be removed. You will need a star screwdriver to remove the screw that holds the cover in place; this is a quick and easy task. Two fuses have been factory installed, those supplied in the carry case are spare fuses.Testing for accuracy : I tested the product against known values. The results were all within the stated parameters.Quality : The product is well made. The actual meter is black and is enclosed within the orange protective encasement, which provides very good protection against the normal bumps and scrapes. The rear of the protective encasement includes holders for the test probes which some users might find useful. The orange protective encasement can be removed. The test leads are of a good quality and include protective caps for both ends of the leads. The display is large, clear, bright and quick to respond; in dark areas it can be temporarily back-lit.Basic functions : DC/AC voltage. DC/AC current. Resistance. Capacitance. Frequency.Other functions : Alarm. Data Hold. Diode test. Transistor test. NCV test. Continuity test. Temperature test. Torch.True RMS : This meter employs True RMS. If you are an electrician or you work in the field of electronics or you are an electronics hobbyist then you know why it is important to use a meter that measures an alternating waveform using RMS. If you only occasionally use a meter to check something electrical in your home then RMS is probably not of importance to you, however, you should be aware that meters that do not use True RMS can, in certain circumstances, provide very inaccurate readings.6000 Count : This is the ideal count as the 6000 count is often considered to be the "sweet-spot" in hand-held digital multimeters as it provides sufficient resolution to catch small fluctuations but is not overwhelmed by electrical noise.Safety : The meter meets CAT III IEC 61010 safety standards.Support : The instruction manual includes information on obtaining support and on activating the warranty.Recommend : YesPurchase again : Yes”
Verified purchase“Well constructed, easy to handle and use, clear accurate readout on display.Used for fault finding on old valve amplifier measuring voltage, resistance and tested capacitors, worked perfectly.”
Seventh on price and second on stars: £33.97 for a 6000-count meter rated 4.7, the joint-highest score in the roundup, from 664 ratings. It is also the heaviest meter here at 820g.
The kit is the reason to look at it. Crenova ships the meter with a K-type thermocouple, a pair of probe test leads, a pair of alligator clip leads, two AA batteries, a carrying box and a manual. The meter itself covers AC/DC current, AC/DC voltage, resistance, frequency, capacitance, continuity, diode, transistor hFE and temperature, with NCV and a buzzer. CAT III rated, double-fused, with a silicone cover and a low-battery indicator.
As a result, this is a bench or toolbox meter, not a pocket one. It is sold on its title as a true rms multimeter, and 664 ratings is a small sample next to a digital multimeter carrying 22,442. The 4.7 is genuine, but it rests on thinner evidence. Skip it if you want light and cheap; buy it if you want the accessories included.
Amazon Basics 6000-Count True RMS Multimeter, IP67
Eighth for IP67 and CAT IV 600V at £23.02, though its bullets claim only voltage and frequency measurement.
Pros
- IP67 rated and CAT IV 600V at £23.02 — the only IP rating in the roundup
- 6000 counts, true RMS, low-pass filter (VFD), max/min, relative and data hold
- Full kit: test leads, 9V battery, carrying case, Type K temperature probe and waterproof jack plug
- 255g and 15 x 4.8 x 7cm — pocketable next to the 550g KAIWEETS
Cons
- The description claims only voltage and frequency measurement — no current, resistance or continuity
- 398 ratings is the smallest sample here
- The bullets give no numeric ranges for current, resistance or capacitance
- Costs £1.10 more than a 6000-count true RMS meter ranked two places above it
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Really good quality, actually worth a lot more than what is currently being sold for. It's solid, IP rated, dial has a good heavy click sound when rotated. This is definitely a professional grade instrument, being an electrician myself for over 20 years I've had a few quite expensive ones, but this is my favourite, just love it actually. Really happy”
Verified purchase“Fantastic value multimeter, it looks and feels really sturdy and has a nice grippy feel.The screen is really bright and easy to read, the cables feel really good quality also comes with temperature probe. Fuses and the battery are easy to change.For £28 all in I am very impressed.”
Eighth at £23.02, and the only meter here with an IP67 rating, alongside CAT IV 600V, true RMS and 6000 counts. It weighs 255g and measures 15 x 4.8 x 7cm.
Even so, the details are good: a low-pass filter (VFD) for variable-frequency drives, max/min, relative and data hold modes, a measurement-saving function and a built-in thermometer with a Type K probe. The box contains test leads, a 9V battery, a carrying case, the Type K temperature probe, a waterproof plug for the jack and a user manual. CE, FCC and RoHS marked.
The odd part is that the description limits itself to voltage and frequency measurements. No current, no resistance, no continuity and no capacitance is claimed anywhere in the bullets. A 6000-count true RMS meter with a CAT IV rating normally implies more. If you need to measure current, buy one that says so. This is the smallest review sample in the roundup at 398, and it costs £1.10 more than the digital multimeter sitting second on this list.
Crenova 606C+ 600A Clamp Meter Multimeter
Ninth because it is the only clamp meter here, handling 600A AC/DC through a 25mm jaw, and it holds the lowest rating at 4.4.
Pros
- The only clamp meter here, reading up to 600A AC and DC through a 25mm jaw
- 6000 counts with true RMS, inrush current, LowZ mode, VFC filter and NCV from 48–250V
- Kit includes probe leads, alligator leads, K-type thermocouple, two AAA batteries and a pouch
- CAT III 600V and IEC61010 with double insulation
Cons
- 4.4 is the lowest rating in the roundup, from 405 ratings
- Its own breakdown shows 4% one-star and 2% two-star ratings
- The 48V AC minimum operating voltage means NCV starts well above low-voltage wiring
- The jaw measures current only — voltage and resistance still need the test leads
What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I wanted aDC capable (Hall effect) clamp ammeter to check on my solar panels and battery. This was the cheapest. I'm very pleased with the package which seems to work well, and comes with probes, thermocouple, and a nice case. The manual is clear and well written.”
Verified purchase“Seems to be ok, the only thing I'd say is one of the popular functions ( continuity with the beep) function needs another button pressing a few times to select it.All in all its a decent tester”
Ninth because it is a different tool. The only clamp meter here, it reads up to 600A AC and DC through a 25mm jaw and is rated 4.4 from 405 ratings — the lowest score in the roundup, and the only one below 4.6. Its rating breakdown runs 66% at five stars and 4% at one star, so more than one buyer in twenty scored it one or two.
In theory the jaw is the selling point: no breaking the circuit, no live contact. It covers AC/DC current to 600A, AC/DC voltage to 600V, resistance to 60MΩ, capacitance to 6mF and frequency to 10MHz, plus duty cycle, continuity, diode, inrush current, a LowZ mode for ghost voltage and a VFC filter for variable-frequency drives. Temperature runs from -4°F to 1832°F with the supplied K-type probe. CAT III 600V, IEC61010 and double insulation, and the pouch, leads, alligator clips and thermocouple are all in the box. It weighs 590g.
Two caveats. Its minimum operating voltage is listed as 48V AC, and NCV detection starts at the same 48V — so it will not pick up lower-voltage live wires. And the jaw measures current only; voltage and resistance still need the test leads. If you mainly check sockets and batteries, a cheaper handheld meter from this list will do the job.
AstroAI 2000-Count Multimeter for DIY and Home Checks
Last despite having the most ratings in the category: 55,860 reviews on a 2000-count meter with DC current only, no capacitance, no frequency and no temperature.
Pros
- £11.99 — the cheapest meter here — with 55,860 ratings at 4.6
- More ratings than the next two meters combined (22,442 + 19,497 = 41,939)
- 1.5V, 9V and 12V battery test modes with automatic status display
- 150g, 7.7 x 13.4 x 3.7cm, with data hold, auto shut-off, backlit LCD, double fuse and silicone cover
Cons
- 2000 counts with no AC current, capacitance, frequency or temperature measurement
- The title says 'Black' while the specification table says 'Red'
- CAT III at 300V is the lowest voltage category in this roundup
- Its 1st place is a Multi Testers sales rank, not a test result — the same listing sits 286th in DIY & Tools

Verified purchase“Brilliant bit of kit for the price, works straight out the box. Does exactly the same as much more expensive models. Can't knock it so far.”
Verified purchase“Used this to test my car battery and alternator and worked perfectly.”
Last, despite the loudest number in the category. £11.99, 4.6 stars and 55,860 ratings — more than the next two meters combined (22,442 + 19,497 = 41,939), and enough to rank 1st in Amazon's Multi Testers chart and 286th across DIY & Tools. It is also a 2000-count meter that reads AC/DC voltage, DC current, resistance and diodes. No AC current, no capacitance, no frequency, no temperature.
In short, it is a battery-and-continuity tool, and it does that job well: 1.5V, 9V and 12V battery test modes with automatic status display, a continuity buzzer, data hold, auto shut-off and a backlit LCD, all inside 150g and 7.7 x 13.4 x 3.7cm. A double fuse and a silicone cover handle safety, and the leads, batteries and user manual are included.
The listing disagrees with itself here too. The title says 'Black'; the specification table says 'Red'. The highlight claims CAT III 300V — the lowest voltage category in this roundup. That is the pattern: a digital multimeter with the biggest review count and the smallest function list. Buy it to test batteries and check continuity indoors. Do not buy it expecting to measure a motor, a heater element or a ring main.
Final Verdict
Buy by job, not by rating count. For most homes, the £21.92 AstroAI TRMS 6000 covers the widest spread of everyday work — mains voltage, current, continuity, capacitance and temperature — and 19,497 ratings back it up. If you want to spend less, the £17.99 AstroAI TRMS 4000 keeps true RMS and adds little you would miss for socket and fuse checks. Anyone working near live cables should take the £29.99 clamp meter instead, because it reads 600A without breaking the circuit. Either way, the best digital multimeter for a job is the one whose ranges match it — a digital multimeter with 55,860 reviews can still be the least capable meter here.

All Tech guidesBest DAB Radios 2026: 9 Ranked, and the 30W Claim That Doesn't Add Up
A radio that claims 30 W of output and a battery that lasts over 10 hours is claiming something the arithmetic will not support. The AZATOM Spitalfields 2 lists 30 W maximum speaker output; the same listing says its 2,000 mAh battery runs for over 10 hours. A 2,000 mAh cell at the 3.7 V that appears in these spec sheets holds about 7.4 Wh, so ten hours averages 0.74 W. At a genuine 30 W, that pack would be empty in about 15 minutes. That is the problem with shopping for the best DAB radios on wattage alone: the Mycket, at £29.99, declares 5 W against a 2,200 mAh battery and 12 hours — around 0.68 W average, the same order of magnitude as the AZATOM. The '30 W' and the '5 W' are not the same measurement, which is why a £29.99 radio looks six times more powerful than a £44.95 one. We ranked nine of the best DAB radios on Amazon on preset count, power source, battery type, display and how well each listing's own numbers agree with each other. Every one of the dab radios reviewed here was checked against its spec table, not against its marketing headline. Price runs from £21.59 to £99.00, and the most expensive model is not the one with the biggest wattage claim.
TechBest CPU Air Cooler 2026: 10 Ranked, One Sold Twice at Two Prices
The same cooler appears twice in this best cpu air cooler shortlist, at two different prices. The Thermalright Peerless Assassin 120 SE is listed at £29.99 with 3,133 ratings and again at £35.90 with 307 ratings — £5.91 more for a name that is identical. The two listings cannot both be right about the hardware: one records 12 Volts and 265 watts, the other 5 Volts and 3 watts. Those watts are not power draw. The cooler's own fan is a 4-pin, 12-volt part moving 66.17 CFM, and the 265 W sitting in the Wattage field is the thermal capacity quoted in the bullet text, not the current the product consumes. The pattern repeats. be quiet! sells two Pure Rock Pro 3 coolers at the same £41.98, yet one lists 3.6 watts and the other 250 watts. Cooler Master's MasterLiquid describes a 394 mm radiator in its copy while its own dimensions field says 15.7 cm long. We ranked ten of the best cpu air cooler options on Amazon on three criteria: the published price and rating counts, the socket support each listing actually states, and whether a product's own specifications agree with each other.
TechBest Case Fans 2026: 9 Ranked by What a Fan Actually Costs
Almost nothing in this list of the best case fans is sold as a single fan, so the price on the page is not the price of a fan. The £21.49 ARCTIC five-pack works out at £4.30 a fan. The £18.66 ARCTIC pack works out at £3.73. Meanwhile the £18.99 be quiet! Light Wings buys you one fan. The same be quiet! Light Wings 120mm PWM high-speed fan is listed twice — £18.99 on its own and £44.99 as a three-pack with an ARGB hub. That is £15.00 a fan, and £11.98 less than three singles. The noise numbers cannot be lined up either: ARCTIC quotes 0.3 sones on both its five-packs, Noctua quotes 25.1 dB(A), be quiet! 31 dB and Corsair 36 dB. As a result the spec tables are not all in the same unit, and Noctua is the only brand here quoting airflow in cubic metres rather than CFM. We ranked nine of the best case fans on Amazon on three measures a buyer can check: the price divided by the number of fans in the box, the specification each manufacturer actually publishes, and the review count behind the star rating. There is no test bench here. Where a listing contradicts itself — and several do — we say so, with both numbers.
