It's a excellent product. If you want all the tecnical data just go to the Mastech page and search the model, if you want more, there is a tear down of this multimeter in youtube it really helped me to decide buying this multimeter. I have used this meter in electronical and electrical proyects, it worked amazingly well in both scenarios. This meter has a lot of functions, my favorite ones are frequency (you can measure %PWM and hz), temperature (of the ambient and the probes, separately), the ports light up indicating the proper way to conect the probes depending on the selected type of measurement (if they are connected wrong it sounds the alarm, great for safety), CAT 3 rated (electrical security parameter), backlight in the screen, quality probes,in general it feels high quality . In summary it worth every dollar.

Frankly, I'm not familiar with "Sinometer". I considered going with a name I already knew, like Fluke.

It turns out I had nothing to worry about.

This is one of those pieces of equipment that you forget you have but because it never gives you a problem. While I mostly use mine for electronics, I have also used it for other Amazon reviews, like this one (http://www.amazon.com/review/R313GN9MC1W7Z9) where I used it to measure the air temperature and humidity coming out of a dehumidifier unit, and also to settle an argument on just how loud or quiet it is.

The function selector doesn't float between setting (a pet peeve). When you switch functions, the appropriate sockets light up to show you where to plug in the the probes. The light goes off when the probe is correctly seated. If you have a probe plugged into a wrong socket, an alarm goes off. How much money (and/or fuses) is that going to save you? I also like the ruggedized kickstand and backlight.

I have a scope... but I usually reach for my multimeter first.

The unit arrived today and I put it to work tracing out a 60's vintage Hallicrafters. Normally I use my Fluke but I left it at my sons (1800 miles away) This unit is amazing it has 1) db sound level built-in 2) temp without and/or with a probe (supplied) 3) continuity with sound so you do not have to keep looking at the meter 4) Lux measurement 5) relative humidity all of which are accurate against my bench units and of course everything you would expect from a multimeter. The batteries are 3 AAA under the stand in the back, remove 2 screws, close the stand so the screws do not fall out, change batteries, close stand cover and raise stand and screw in primary cover. This unit is well thought out well laid out and inexpensive to boot. I called my son told him he can keep my Fluke. O' one last thing, when you turn the selector switch the surround around the probe inputs lights up to help from making a mistake, the manual is actually readable and to the point. I will update as time goes on but the Hallicrafters was working like new with the help of this meter. The designer did as good a job as I have seen of "stupid proofing" a Digital Meter.

A decent meter for the price, but could use simple improvements

Reviewed in the United States on February 1, 2015

Verified Purchase

This meter seems to be pretty good. I don't know how accurate it is, but I don't really require great accuracy these days, mainly consistency and ease of use. I used to be an electronics repair tech long ago, where accuracy was important, but no more. Anyway, it does seem to be consistent and the results seem to be in the ballpark. I probably should have gotten something cheaper, but the specs for this sounded good.

However, I think it's a little too big, although that's just personal preference. At least the display is easy to read. It seems pretty durable, but not as durable as it looks in pictures - the padding is not particularly soft, and doesn't provide as much protection as it might seem by looking at it.

It's nice that it has a place for the probes on the back, and I also like the way it lights up the jacks depending on the function so you know that you have (or don't have) the correct ones connected. Just be sure to press in the plugs firmly, as once I realized that one was not all the way in, and the readings were weird.

The layout is a bit complicated and not very well thought out. All buttons are the same size. It seems to me that some less-used buttons should be set aside or smaller. I never switch the degrees C/F (in fact, I haven't even used that function) and rarely need the Relative button, so it would be nice if the Range and Select buttons were bigger, and separated.

I also think that the Volts and Ohms would be better placed on either side of the Off position, since they are the ones used the most, but maybe others would use other functions more, so that's a tossup.

The flip-out stand is a bit flimsy and not very stable. The battery compartment requires removing screws.

Great instrument for the price. I use the temperature and humidity for recording conditions doing insulation tests on wiring. The light level function comes in handy for monitoring temp lighting on construction sites. The sound level is useful for determining the need for hearing PPE, and perhaps for Fire Alarm NAC device coverage. This is a useful instrument for the construction electrician.

Received this little gem this morning, added 3 good quality batteries, and tried a few different tests. All worked as one would expect. Maybe it's not the top end Multimeter that start above the $300, but more than adequate for most handyman shops when you need a meter two or 3 times a year or a half dozen times like me. Did quite a bit of research and checking reviews, Utube, etc before choosing this Mastech Multimeter but it just seemed like it offered everything and then some, as it never fails sometime down the road that's the feature you'll just need once in a blue moon, but this time you got it... Dam good deal..

Todo funciona genial, excepto la función de continuidad (beep)

Reviewed in Spain on June 19, 2017

Primero, diseño y construcción. Los materiales son buenos, cuando lo ves, sabes que estás ante algo mínimamente decente. La calidad de construcción es muy buena, pero tiene 2 fallos: la rueda/selector, aunque funciona genial, si somos un poco tiquismiquis podemos decir que es mejorable, ya que puede quedarse a mitad de camino, la sensación de rotación no es tan, tan buena como la de otros multímetros más caros, etc... y lo que sí está mal diseñado es la goma verde de alrededor. Esta goma se puede quitar, pero el problema no está en el montaje o desmontaje. El problema está en que cuando está puesta, la lengüeta o ranura que engancha a la goma por los laterales es muy pequeña, y se puede salir de su sitio, y estéticamente queda feo. Es gracioso, porque en las fotos del producto, aquí mismo en Amazon, puedes observar en los laterales cómo la goma está salida. Es un error puramente estético, pero no debería pasar. El resto del diseño, los agujeros de las puntas, los botones... todo perfecto, muy bueno.

En cuanto a la pantalla, aunque tenga la gran característica de ser retroiluminada, los ángulos de visión son bastante deficientes. Tampoco es muy importante, puesto con la pata trasera sacada y apoyado en la mesa, desde una silla se ve perfectamente, pero en cuanto lo movemos un poco al lateral o arriba y abajo, la visibilidad de la pantalla empeora una barbaridad, los números casi desaparecen. Es una lástima, deberían poner una pantalla que tenga mejores ángulos de visión, se nota sobretodo cuando trabajamos de pie.

Respecto a funcionalidades, está muy, muy bien, tiene de todo, incluso en la pantalla puedes ver la temperatura y humedad del ambiente, es genial como referencia, además de tener un sensor para medir temperatura de forma más precisa. Los agujeros se iluminan alrededor para que sepas dónde tienes que poner las puntas, y aunque no sea del todo necesario para los expertos, le da un toque moderno, evita que te equivoques y además pita y parpadea en rojo cuando las puntas están en agujeros que no corresponden, lo cuál para medir ciertas cosas puede ser peligroso (por el fusible que te lo puedes cargar, el multímetro también, o incluso hacerte daño tú mismo). A mí personalmente me parece un detalle muy curioso y se agradece mucho.
Hay un gran fallo con una funcionalidad, que es la de encender la luz de la pantalla. Se enciende pulsando el botón de HOLD durante 3 segundos. El problema está en que cada vez que quieres encender o apagar la luz de la pantalla, la función de HOLD se activa, y tienes que pulsar el botón de HOLD una vez más para que deje de mostrarte la misma lectura congelada en la pantalla. En resumen, para encender la pantalla, mantienes presionado HOLD, esto inmediatamente te congela la lectura de la pantalla actual, y posteriormente se enciende la luz. Luego, tienes que darle otra vez al botón HOLD para descongelar la lectura.

Las puntas que vienen son geniales, son de calidad, las coges y no son las típicas de plástico duro barato, además de que traen protectores en las puntas para dejar sólo la puntita al aire. Otro punto fuerte es que la punta es bastante afilada, y eso se agradece porque puedes tocar cosas con más precisión.

El mayor problema que he encontrado es que en la función de continuidad, el pitido, aunque es rápido, es DEMASIADO sensible, y no uso sensible como cosa positiva, sino como negativa. Aún cuando las puntas se están tocando y hay CLARAMENTE continuidad y debería oírse un pitido constante, resulta que no, que el pitido es interrumpido bastantes veces, sobretodo al frotar una punta con la otra. Esto es un error, de gravedad media si hablamos de la función de continuidad, donde realmente buscas definición y exactitud en el pitido. La ventaja es que es bastante rápido. No obstante, multímetros de 200€ o más caros son claramente superiores en esta función. Cuando las puntas se están tocando claramente y se frotan, el pitido es constante y no se altera. Además, la respuesta es aún más rápida. Esta función en este multímetro es mejor que dicha función en multímetros de mala calidad de 8-30€, pero se queda a medio camino de ser decente, una lástima.

Viene con pilas (no siempre) y el fusible que trae he leído que es de calidad baja, pero bueno, servir sirve, y siempre se puede cambiar.

Reviewed in Italy on June 3, 2017

Il prodotto arrivato è il modello MS8229 e non il modello MS8229G ma questo è un bene in quanto il modello caratterizzato dalla lettera G ha caratteristiche inferiori al modello che mi è arrivato.
Ottima la funzione di illuminazione delle boccola dove inserire i puntali in funzione delle varie portate scelte con il commutatore e ancor più l'allarme sonoro in caso di inserimento errato, sembra un gadget inutile per utilizzatori esperti ma invece ho sperimentato che è utilissimo in quanto la distrazione è sempre possibile e una sicurezza in piu' non guasta, oltre al fusibile autoripristinante e il fusibile ceramico per la portata di 10A. Struttura robusta anche se un pò massiccia. Apprezzabile la funzione fonometro, luxmetro e termometro interno ed esterno e addirittura igrometro, che possono sempre essere utili anche se, chiaramente, per uso intensivo è meglio utilizzare strumenti dedicati.

Great budget multimeter perfect for the hobbyist

Reviewed in the United Kingdom on February 2, 2016

Verified Purchase

So I was going to try and purchase a rather expensive Fluke 87V... but instead opted to save my money.

As a foundation radio ham I needed a decent multimeter to perform some basic electronic diagnostics and help with my progression to the intermediate level. This I feel was a good fit for me. Relatively cheap compared to the Fluke and in no way is it going to be an amazing count multimeter for hyper accuracy or precision but it's ideal for the hobbyist or doing some basic home electrical troubleshooting.

Auto Ranging is a feature i've not had on a multimeter before and I can safely say I love it.
The backlight and display is clear and easy to read, with multiple useful values displayed at once (e.g. duty cycle + frequency of signal)
The light up probe ports are a novelty but actually rather useful.
The inclusion of a basic thermocouple to perform basic temperature measurements has actually proven useful when monitoring some stepper motors for overheating issues.

It can measure lux from emitted sources along with relative humidity and air temperature all of which I've actually found useful since buying the device (never thought I needed it before... but seeing as I had it I used it anyway! :)).

All in all a fantastic device. The casing is good, robust and rubberised with a neat "home" for the probes, which are sharp (great for testing through insulation) and CAT IV approved. Should prove to be a useful device for a long time to come.

Ce multimètre me permet de travailler en sécurité, afin de vérifier avant toute intervention si j'ai du 220V sur une prise (j'ai préalablement fait tomber le fusible, mais je vérifie toujours par sécurité).
Je l'utilise aussi pour détecter la continuité (vérifier une ampoule, si l'ampoule a grillé ou bien si le problème est ailleurs).
Enfin, je mesure des résistances pour les quelques circuits électroniques que je monte par moi-même.

Le multimètre est costaud, agréable à manipuler. Le bouton se tourne très facilement.
L'affichage digital est rétroéclairé, un plus non négligeable quand on travaille dans la pénombre (habituellement, si on fait sauter les plombs, on n'a plus de lumière autour de soi ou une lampe frontale).
La fonction "HOLD" permet de retenir la valeur lue, c'est un avantage par rapport à d'autres appareils qui ne disposent pas de cette fonctionnalité.

Pour finir, les sondes sont un élément clef de ce genre d'appareils, afin de ne pas engendrer de perturbations. J'ai bougé les sondes dans tous les sens, cela n'entraîne pas de variation significatives des valeurs lues, ce sont donc des sondes de qualité. Le petit bouchon qui permet de les protéger est garant d'une bonne qualité, si vous ne les oubliez pas ou ne les perdez pas après usage...

Si vous appréciez ce commentaire et que cela vous a été utile, merci de me le faire savoir en cochant OUI ci-dessous.
