TM-510 Digital Multimeter, 4000 Counts, Smart Measurement, Auto-Ranging Voltmeter; Voltage Tester with Non-Contact Voltage Function, Measures AC/DC Voltage, Resistance, Continuity – Green

Just like the title says, this is a great value for your money. if you need a simple to use, I mean very simple to use inexpensive multimeter, this is the one. It's virtually foolproof to use! Anybody who has never even used a multimeter can start using this one from the get-go. All the functions are automatic, AC/DC voltage, resistance and continuity. I've used it to check voltages around the house and it's performed flawlessly. I haven't yet checked resistance as I'm not a power user to have resistors laying around. It also has a feature to check electric plugs/wires to see if they are live wirelessly, it has a backlit display and a very small LED flashlight. To be honest the flashlight is super dim, but hey! It's better than nothing I suppose. It also has nice build quality and like I said, it's a very good basic foolproof household multimeter.It was very nice also that it came with genuine copper top brand name batteries, a carrying case and a very well-written instruction book that was very detailed and concise in explaining its use. Amazing how fast technology advances as a multimeter like this would have been over $150.00 years ago and so far, I'm very happy with it. And for the price you really can't beat it. And say goodbye to those old-fashioned dial multimeters that were honestly such a pain to use. I highly recommend this Tesmen TM-510.

No, it is not industrial quality. And yes, it probably is not something a professional would use for day to day applications. But it's a great economical, (and pretty sophisticated ) little meter that can handle the basic tasks of a homeowner with ease. Let's define what I mean by that last sentence before going on, for all you "Pros" out there: checking to see if an outlet has power or not. Making sure that you turned off the right breaker. Checking for continuity of wires, say going to and from your speakers to an audio source. Is your laptop broken or is the power brick bad? Is it the fuse or is something wrong? There are hundreds of uses for something like this, and the features of this particular economical meter take the guesswork out of setup/use.The Non contact voltage detector on this unit works better than any I have previously used. A great safety feature that can be used by anyone. It lets you know as you approach a dangerous voltage without having to use probes. All other functions are completely automatic, so no more worries about the wrong function or the wrong range or having leads plugged into the wrong location. It does the work for you. Accuracy on voltages compares well to my other meters. The only thing I found about it that I didn't like is it's a bit quirky to get the backlit display turned on without messing with the built- in flashlight; both are good features, but controlled by the same button. One more issue which some others addressed; it does not have current measuring capabilities. And that's a good thing for the average homeowner because attempting to measure current is how the occasional users blow up meters. Period.This is a very nice meter for the money, and way, way above the little 5 dollar ones still being sold or given away; all of which are built with 30+ year old technology. If you are into 480 3 phase, a licensed electrician, or you're a lineman for the county, then keep looking.

As someone with no electrical background, I was a bit intimidated at first, but the TM-510 Digital Multimeter has been an absolute game-changer! This device is incredibly user-friendly, even for a complete novice like me. The smart measurement feature automatically detects what I’m testing—voltage, resistance, or continuity—without me needing to fiddle with settings. The display is clear, bright, and easy to read, and the non-contact voltage function is a lifesaver for safely checking wires. It feels sturdy, well-made, and comes with everything I need, including probes and a handy carrying case. I’ve used it for simple home projects like checking outlets and troubleshooting battery-powered devices, and it works flawlessly every time. This multimeter has given me confidence to tackle small electrical tasks, and I highly recommend it to anyone, beginner or not!

This multimeter was great. High quality, cheap, and very portable. Functions well, however, I took off a star because it was slightly difficult to change modes, but I eventually was able to. Just a slight learning curve. Other than that, it's great!

An easy to use, read, and surprisingly good multimeter at this price point. If you are looking for a multimeter that does it all , this is not it. But for checking voltage, resistance, and continuity, this little product does the job. Unlike, most multimeters, to check your AC or DC voltage there is no switching or changing leads. Same goes for resistance and continuity. I do have a very cheap multimeter that does more, but it is not nearly as simple to use as this one Highly recommended.

I was quite suprised by the functionality and features on this excellent volt/ohms meter. It does everything discribed by the vendor and it even comes with Duracell batteries, a nice carry pouch, a protective case and a nice owners manual. This meterr is an excellent value for the home user, hobbiest, or professional mechanics who doesn't want to pay tool truck prices. I would buy again in an instant and highly recommend.

Works well. As advertised, it is automatic which is nice and great for beginners, however there is no option to change to a manual mode if you're looking for thatThis has an audible continuity tone/beep even though it wasn't advertised.Easy to use and cheap.
