Best PeakTech multimeter
Updated: 22 October 2026
You want one PeakTech meter named for a job, and a reason to leave the other three. Stars will not do that. Both handhelds sit at 4.5, and the clamps sit at 4.1 and 4.2. The best PeakTech multimeter here depends on whether you need a CAT IV logger, a 4–20 mA handheld, milliamps in a closed cable, or a 400 A jaw. The [PeakTech multimeter comparison](/hub/measuring-equipment/peaktech-multimeter) holds the table. This page says who each listing is for, and who should skip it. The Products Compared editorial team used the four amazon.co.uk listings scraped on 21 October 2026. We did not lab-test them. A qualifying purchase through our links can earn a commission at no extra cost to you.

Best for a CAT IV handheld with a logger
The top pick for a graphic logger is the P 3440, B01MA3UBJM, at £204.17, with 4.5 from 260 reviews. It prints CAT III 1000 V and CAT IV 600 V, a 50,000-count colour screen, Bluetooth 4.0 and an on-meter logger. Three UK reviews describe plant equipment and electric forklift circuits, a screen readable in bright light where an LCD was not, and a pack still charged after four months of daily use. The same notes say the continuity beep takes almost a second and that the materials do not feel like a Fluke. The title says Li-Po 1200 mAh; the INFO line says a 7.4 V Li-Ion battery and a charge adapter, and the plug is unstated. One bullet prints P 3340 while the model number prints P 3440. PeakTech states 10 A and ±0.05% DC basic accuracy; Amazon prints no ampere limit. If you want the filter more than the colour logger, the next section is the P 3442.
When the P 3442 is the better buy
Choose the P 3442, B07DW6PG4P, at £162.90 when you want CAT IV on an LCD handheld and you will use 4–20 mA% or the low-pass filter. It is 4.5 from 163 reviews, switchable up to 60,000 counts, with Bluetooth 4.0 and Auto-Hold. A UK review from 7 July 2019 says the Android app worked, the leads were longer than 1 m, and the meter was used on mains, microamps and millivolts. The same review says the strain relief was unimpressive and that a laptop needed the supplied dongle. That buyer also reports a certificate, a CD and a dongle, none of which are in the INFO line. A second UK review is only the words Great meter. A non-UK review reports a display fault after about two years. PeakTech states 10 A and ±0.9% DC; Amazon names current without an ampere limit. A search on 21 October 2026 did not put this ASIN in the first results for “PeakTech 3442”, so this page uses the scraped price. If the current is inside a closed cable, leave both handhelds.
Best value when the current is in the cable
The best value pick for small-conductor current is the P 4350, B01M0AQ0UE, at £75.18. It is an 80 A AC/DC True RMS clamp with 1 mA resolution up to 5 A, 100 mA resolution up to 80 A, and a jaw for cables up to 12 mm. The star line is 4.1 from 142. No UK review text appears in the first 50 bodies, so the comments are from Spain, Germany, Italy and France on the same listing. They use the milliamp range for RCD leakage, vehicle quiescent current and a motorcycle charge lead, and a French review says the REL control has to zero the clamp. The same sample reports drift after that zero. The listing prints CAT III 600 V. CAT IV and TÜV / GS are not stated. The price is why it is the best value, and the drift reports are why you skip it if the low range must sit still. A core fatter than 12 mm points you at the 400 A clamp.
The 400 A clamp, and when to leave it
The P 1650, B00664VE90, at £77.70 is the title that states 400 A AC/DC. It is 4.2 from 88 reviews, with data hold, a Type K probe and CAT III 600 V. The only UK review, 24 June 2026, says the battery arrived flat, so that buyer never saw a reading. Non-UK texts split: one reports a lab check inside tolerance, another says the figures would not repeat, and several mention a voltage with nothing nearby. The title says 4,000 counts; the INFO line says 3,999. The power field says electrical (wired); the same block says alkaline batteries are included. The scraped table has no jaw size. A later line on the amazon.co.uk page adds “up to 30 mm” and “100 kHz”, while PeakTech states 30 mm and prints two conflicting frequency figures. An extra £2.52 and a 400 A title do not make this the best value. Leave it when you need 1 mA resolution or CAT IV.
Listings this page will not crown
Amazon’s wider search shows meters this comparison does not keep. The P 3315 is often unavailable, with a CAT IV claim and 4,000 counts. The P 4095 is a bench meter marked CAT I and CAT II. The P 3432 is a Schuko fuse finder, and a Schuko face is not a BS 1363 socket. Lead packs are accessories. If you still need the check order, use the buying guide. Jaw versus leads is on the clamp page, and the zero button is on the how to use page.
Common questions
Which one is the top pick, and for what job?
The top pick is the P 3440 when the job is a CAT IV handheld with a colour logger. It is £204.17 and 4.5 from 260, and the UK reviews mention plant equipment, forklift circuits and a screen you can read in bright light. Skip it if a continuity beep of almost a second will slow you down, or if you need a charger plug the listing actually names. It is not the meter for a 12 mm leakage clamp or for an Electrical Installation Certificate.
Is the P 3442 the one if I do not need a colour logger?
At £162.90 it keeps CAT III 1000 V and CAT IV 600 V, and the bullets add 4–20 mA% and a low-pass filter. One detailed UK review covers mains, microamps and a laptop dongle. The other UK text is two words. A non-UK review reports a display fault after about two years. PeakTech states ±0.9% DC basic accuracy here, against ±0.05% stated for the P 3440, and Amazon prints neither percentage. The thinner UK sample is the limit on this recommendation.
Which is the best value if I need milliamps in a cable?
The P 4350 at £75.18, if the cable is within 12 mm and you will zero the jaw. The listing states 1 mA resolution up to 5 A. That is the best value mark because of the price and that claim, not because the written reviews are British. The first 50 bodies have no UK text, and non-UK reviews report drift. CAT III 600 V is the printed category. The P 1650 at £77.70 is the wrong bargain when the job is 1 mA rather than 400 A.
Is the P 1650 the one for 400 A?
It is the only title here that states 400 A AC/DC, at £77.70 and CAT III 600 V. Use it on one conductor when that category is enough and you fit a fresh battery first. The only UK review says the cell was flat. The listing disagrees on wired power versus alkaline batteries, and on 4,000 versus 3,999 counts. Jaw millimetres are missing from the scrape and stated as 30 mm by the maker, beside two frequency figures.
Do UK reviewers say it feels like a Fluke?
One UK review of the P 3440 says the materials do not feel like a Fluke, and that buyer still called the price acceptable. That is one comparison, not a materials test. A non-UK note on the P 3442 says the display looks less clear than a Fluke. The P 4350 sample has no UK text, and the P 1650 has a single UK review about a flat battery. Feel is a reason to handle the meter, not a score you can average.
Did anyone in the UK review the P 4350 in the sample?
Not in the first 50 review bodies. The public line is still 4.1 from 142, which mixes every country on that amazon.co.uk page. Themes such as RCD leakage, vehicle quiescent current and REL zero come from Spain, Germany, Italy and France. They are reports from the same ASIN, and they are not a UK review count. If you need British written experience before you buy, this listing does not provide it in the sample we kept.
