ExtechEX355 True RMS Professional MultiMeter with NCV and Temperature Measurements

For a unit that has all the functions this one has, it is a great buy! I would recommend it to anyone who has the patience to wait for the accurate response. It takes time for the meter to display the correct reading. If you are impatient you may not get the final (correct) display information. The display changes over time as it adjust for accuracy. It would be better if it did not display any value other than 'processing' while calculating the results. But it appears to be very accurate. The time delay does make continuity checking difficult. I would have only rated it 3 stars for that reason. However, given all its functionality, that set back is not as much of an issue! I'd say buy it and deal with the delay! For the price it is a no brainer!

Just a couple of notes...The orange cover is rubberized and protects the green plastic meter.You purchase additional/different leads - lookup Extech TL809 and you can see the different lead kits that are available.The backlight doesn't stay on when you turn it no. You have to press and hold the button for a few seconds for the light to come on, and while it's on you can press and hold it for a few sends to turn it off (all good). Unfortunately once you turn on the backlight it will automatically turn off after 15 seconds (disappointing).For some (annoying to me) reason, the unit beeps for each click as you rotate the dial to different functions. You can hear and feel the click so I don't know why it needs to beep too.Some have reported that it doesn't have a beep for a continuity tester, however it does have one. You have to select the correct mode (using the LPF/M button) to hear the beep.It comes with a CD with the Users Guide in a PDF file (it also comes with a pre-printed Users Guide).Extech has their own web site.

After thourough research to get the best bang for my buck, this was the winner hands down. It is a great balance between functionality and capability. I have found it has more than met all of my needs for it. I am only a hobbyist, but I feel safe with this meter, and it works great. I highly recommend it for anyone on a budget.

I left my beloved Simpson 260 in the office of a client over Thanksgiving weekend. The place was broken into and my 38 year old Simpson was part of their booty. That meter had survived 38 years of near constant travel--all 50 states, most of Europe and a good deal of Middle East and some of Asia. I am old school and OLD, so that meter was ideal.Go digital, everyone said. Fluke is great, but over priced they said. So I purchased perhaps the slowest multimeter in the universe. Yeah, it has lots of features for the $. About 1/3 the cost of a similar Fluke. It works, but it is sooooo sloooooow. I started doubting myself when testing it out. Why no reading? Oh, go get a snack or a drink and then you might see the digits. Of course that is a stretch, but this much is true, the time to read either voltage or resistance in real life WORK situations is indeed slow. I expected some slow compared to the analog Simpson. But, on a major check out, it grew tiresome waiting on the meter EVERY point.The more "bench" stuff, cap, and resistor testing is nice and a bit slow. To me, it was less of an issue in those modes. Side by side with an old GW//Instek bench DMM, the accuracy was right on the money.Backlight is a real issue. Have to turn it on....and have not found how to keep it on for any length of time. Big issue for some of what I need it for.Menu structure and keystrokes seem ok. Not the most intuitive, but then I am used to an analog meter. So I can accept some learning curve.Still on $75---not throw away, but not great value. For occasional use, it should be just fine. But there is, I have learned, a reason you see real Pros using Fluke. I try not to be swayed by a brand, but based on my early use of this unit, I can see why a pro would be disgusted with it in about 5 minutes.Again, you get what you pay for and if you are a limited user and have a tight budget it does offer a lot of features for the price. That reminded me that selecting tools is not just specs and $ to balance---you have to think about how you will use the equipment. Slow and no backlight (no always on for backlight) have colored my view of the unit. Perhaps that says more about my failure to research and test then it does about the meter or manufacturer.Not gonna send it back. It just might be the tuition I have had to pay to find what will serve me like my old Simpson did.

A surprising little find. I was planning to replace my cherished and lost Kewtech 117 which served very me well. After a little Amazon search this offering from Extech popped up - which to be fair I initially dismissed due to being an unknown brand to myself, but, the additional option of a thermometer got me interested, so after a little googling for reviews I found it’s parent company was Flir - well known as a go to brand of high quality TIC’s, so I thought, why not, I’ll give it a try, and I’m glad I did.It provides all the offerings of the Kewtech, the readings displayed match those from my previous DMM (verified on known values as part of my test instrument quality control for my Megger MFT 1741+). (Sorry chaps in the Metrel eurotest club) The temperature values displayed are very similar to my Bosch GTC600 TIC readings and the built in no contact voltage detector is a lovely little touch - just a little bulkier than a volt stick. The Loz function for squashing inductance readings often found in AC dead circuits where similar singles are in the same trunking has its merits, whereby all this is cheaper than the Kewtech and nicer than my old original Fluke 77 series II. My only minor criticisms are, you’ll need to chuck a decent set of leads with 4mm bananas for swapping out crocks and fine tips, no ability to turn off the confirmation bleep when changing scales or functions and a decent thermal probe if you do water temperature tests / Air-con etc, (type K) which means giving another £45 ish plus VAT for the privilege if you don’t have one already.

Ich hatte zuvor die Multimeter von KAIWEETS (ca. 45€, True RMS Auto-Range 6000 Zähler,) sowie von AoKoZo (ca. 22€, 21D Multimeter 6000 Counts, True RMS) in den Händen gehabt. Die Anzahl der positiven Bewertungen wundern da einen schon.....Diese hier ist kein Vergleich zu den vorgenannten Geräten. OK, es kein Fluke und mehr als doppelt so teuer wie die zuvor genannten Geräte. Das sollte jedem klar sein, aber das Multimeter ist genau das was ich gesucht habe. Es misst schnell und genau, hat viele Funktionen und fühlt sich in der Hand wertig an. Gut, die Farbe der Außenhülle ist nicht so mein Ding, aber die inneren Werte stimmen. Ich bin sehr zufrieden mit dem Messgerät und bin froh, die günstigeren Modelle nicht genommen zu haben.

Il prezzo è diverso ma la qualità si paga. Dopo due multimetri cinesi ritornati indietro (grazie Amazon!) ho comprato questo e ne sono pienamente soddisfatto. L'unica noia è che di default all'accensione è in AC invece che DC come ero abituato io.

Very happy with this instrument. Very responsive and fast for measurements. Capacitance and resistance are on upon testing with 0.01% capacitors and resistors. Only had to give the probe tips a clean with fine grit sandpaper and a wipe with rubbing alcohol in order to have a quick latching continuity function. Feels very solid with a very nice and thick rubber casing and nice build quality. The probes are also good for their insulation and overall quality. There is also a nice click on the range selector switch that makes it hard to be in the wrong range. Overall, love the instrument and would recommend it 100%.

Well built. Provides accurate, consistent, stable and fast measurements. Nice LCD display. The function diaI is robust (not flimsy like many DMMs). Hope it will stay reliable over time.UPDATE (2022-02-03): On two unrelated events, the multimeter provided inconsistent measurements while using the resistance scale. For example, I was expecting less than a couple of ohms on a disconnected 10-foot copper wire (20AWG) but the measurement was about 80ohms. What? I therefore checked all my measurement connections many times (disconnect, reconnect), cleaned the probes, moved the wire around, turned OFF and ON the multimeter. I was still getting about 80ohms !!! I then left for 2 minutes and when I came back the multimeter was displaying 0.6ohms as it should be. I then tried to provoke the bad reading again without success. As I already said, this type of incorrect measurement happened to me at least twice recently.
