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

I am a diesel mechanic and use this often, this is a reliable small, simple design and inexpensive multimeter that is very helpful for diagnosis. The product offers a audible sound for testing resistance, even a flashlight! and also offers non contact voltage detection feature which comes in handy when searching for a wire through a wall or surface. It functions very well and would recommend If you just need a small multimeter with simple features. The only downside I've noticed is that you cannot select your own mode as it is all automatic but still gets the job done right.

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!

Comes in reclosable box and zippered storage case. The zippered case has a pocket to store the leads. I was surprised it came with 2 Duracell AAA batteries instead of the usual generic ones. I tested the NCV function near a plug socket and worked great show an H for high voltage. Also used it with leads on the socket and worked fine. Tested an 1.5V AA battery with it and displayed 1.47 so seemed accurate. The multimeter has a rubbery or silicone removable outer casing to help protect it. It's lightweight and easy to use. You can press a button to backlight the screen or turn on a small LED light on the back. CONS: Has one of those tiny screws to hold on battery compartment cover. Not so convenient to unscrew as you need a screwdriver small enough and I can see the screw dropping and getting lost. Would have preferred LED light on top of device so easier to aim the light and read in the dark. Now realize I would have preferred a non-automatic multimeter where I could select the function, but that's my fault. Overall good multimeter and the automatic function is probably great for basic home user.

As a homeowner, it is perfect for my needs. I put the batteries in and it immediately turned on. The instruction manual is written really clear. The meter worked right out of the box. All functions worked. The smart meter makes it very easy to use because you don’t have to fiddle around with guessing the correct range. Very pleased with the meter and its ease of use.

Saw on TIk Tok and thought I would give it a try. I used it on a good bit of diag on electrical issues on truck, trailers, and equipment. Really easy to work and user friendly especially if you’re getting started out. Small enough to put away in a crammed tool box with no issues. Highly recommend for beginners, DIYers and professionals.

Tout est parfait. J’ai rapidement compris comment l’utiliser, l’interface est claire et intuitive. Je l’ai déjà testé et tout fonctionne impeccablement. Très bon rapport qualité/prix !

Looking a bit cheap and nasty, spent a little more on a quality product 👌

Das Multimeter macht einen soliden und wertigen Eindruck und liegt gut in der Hand. Die Messwerte werden schnell und gut ablesbar angezeigt, was die Arbeit deutlich erleichtert. Für typische Anwendungen im Haushalt, in der Werkstatt oder beim Hobby ist es mehr als ausreichend ausgestattet. Insgesamt ein zuverlässiges Gerät

This is a good tester, and volt meter, it works as it should and is verry accurate. Comes with everything you need and it also has a built in sensor for tdetecting low and high ac current without using the tester probes, just doesn't tell voltage unless you use the tester probes. Small and light weight, very easy to use also. This digital multimeter is a excellent value for the money that I paid for it. And it will also test a fuse to see weather the fuse is blown out or not. A very useful tool indeed.

Usado para bricolage casero y vehiculos. Medidas reducidas , 12 ×6 cm, × 2,5 grosor .usa 2 pilas AAA (las delgadas) .Trae manual muy claro en castellano. Tiene una funda de caucho protectora para caidas. Tres botones para seleccionar. Boton central enciende el aparato en modo automatico (apagado en 15 minutos si no se usa) Detecta automaticamente la corriente , dando la lectura correspondiente con unos digitos en pantalla de buen tamaño ; por lo que se puede hacer una medicion en un enchufe de 220 ac. ...y a la seguida medir una bateria de 12 v cc sin tener que selecionar nada , y a continuacion medir resistencia , que nos dara la medida en onmios , o la continuidad con un fuerte pitido. Boton derecho , enciende una pequeña luz linterna trasera ,y -o enciende la retroiluminacion de pantalla ( que es lo que yo siempre uso) . Boton izquierdo ,detecta corriente al acercar el aparato a fuentes activas ,encendiendo una luz roja y dando pitidos , este boton tambien nos permite congelar una medicion , si lo aplicamos cuando estamos haciendo ésta en automatico. Estoy encantado con él. Los simbolos que aparecen en la foto del producto , son todos los posibles que pueden aparecer en las diferentes situaciones que se den , ...no es que aparezcan todos al vez.
