Hantek 2D42 Oscilloscope, 40MHz 2CH, 25MHz Waveform Generator Multimeter | 3 in 1 Multifunction Tester, 2CH OSC + 1CH AFG+DMM

Bought because I dropped a hammer on my crappy multimeter and I've been looking for an excuse to get a new one, I really wanted an oscilloscope too but we all know how expensive they are. I honestly don't really use the oscilloscope feature a whole lot but I have used it once or twice and it works pretty good, the user interface is a little confusing but once you know how to use it it's great. I wish the packaging was a little bigger because after you take all of the accessories out it's kind of a pain to get them back in addition to the DMM. Multimeter does exactly what it says it does, It works. My only real complaint about the whole thing is that the screen turn off time sometimes gets in the way of something that I'm doing, I think you can turn it off so that's not really a huge issue but also it's not very good with when the sun is reflecting off of it, I usually have to find a specific spot for it when I'm doing something or else the reflection of the Sun will just make it completely unreadable so I just keep it in the shade most of the time. Overall it's very solid, works great, I don't know if there's any type of circuit protection built into it but I feel like they're probably is because I've definitely done some things at some point that should have popped a fuse but it just didn't, very nice device and honestly My only regret was not getting the highest tier one even though I'm sure I wouldn't have used whatever that extra thing was, I'm just like that I guess. 10/10

-Lo he utilizado por un par de semanas, y por el precio, creo que es la mejor opción calidad-precio para tener un osciloscopio de buena calidad y además portable. -Viene en un estuche semiduro que es bonito y de buena calidad (la disposición de los elementos dentro del estuche es diferente a la que mostré en las fotos, son fotos después de usarlo por un par de semanas). -La punta para osciloscopio es de calidad media y recomiendo comprar una por separado, es bastante ligera y frágil. -Las mediciones son rápidas y precisas, pero la función de Autoset es un poco lenta. -Es posible conectarlo al PC por USB para usarlo con una interfaz más rápida, pero los datos entre el multímetro y la aplicación se envían cada segundo y es algo molesto. -Es necesario cargarlo al inicio porque vino totalmente descargado, y tarda alrededor de 2 horas en cargarse completamente. -Las mediciones con el multímetro tienen una tasa de refresco un poco baja, pero tiene buena precisión. En conclusión, dentro de lo que he podido probar, es una de las mejores inversiones que he hecho en cuanto a osciloscopios de bajo costo (comparado con osciloscopios de banco), considerando que además hay generador de funciones, teniendo en cuenta que tanto osciloscopio como generador de funciones comparten la misma tierra, obviamente, y para algunos circuitos esto puede ser problemático.

This was portable and well suited for analyzing power problems in my RV.

Works good enough that if it breaks in the field I’m not worried

Es un instrumento de prueba electronico que se usa para reparar equipos electronicos, funciona muy bien

Haven’t used it much but it does the job and is handy to have around. A good selection of accessories.A little bit tricky to access some settings.

acorde con su precio sus beneficios y caracterisiticas.

I purchased this handheld oscilloscope to allow me to pursue hobbyist electronics projects and to help me repair an old vacuum tube radio. This oscilloscope has the necessary speed, resolution and features to do that and more, and I've been generally pleased with the unit. As others have mentioned, the interface is a bit odd in places but certainly gets the job done. The resolution and sample rate are certainly good enough for electronics in the few-Mhz range, which covers most hobbyist and radio applications. The more recently refreshed unit is still well-built and has a brighter screen. The "updated" firmware is old now, but still an improvement over the original version. The wave generator is a very welcome feature and well worth the additional money. Having both an oscilloscope and a multi-meter in the same unit is very useful, because I only need one tool for a variety of applications. However, one star was removed because the quality control is not great - one of the two included probes arrived with a missing calibration screw, and I cannot adjust the compensation on that probe. While the probe is technically usable, it is not completely accurate and never will be. One more star was removed because, as MANY customers have stated, the manufacturer's customer support is basically non-existent. Multiple emails go completely unanswered, so there is no way to get support that way. The support phone number listed on the site is in China, so you must pay for international calling and call during a brief window of open hours in their morning, and even then I wasn't able to talk with anyone who understood English. So, if you purchase this oscilloscope, you need to accept that any and all support will be through the community, or through the reseller - the manufacturer will NOT support you.

Llegó antes de tiempo. Bien empacado trae todos materiales que mencionan y funciona muy bien, todo está en perfecto estado. Lo ocuparé para mí carrera y estoy muy feliz

bis jetzt in 15 Ländern verwendet und für mich genau das richtige. Damit macht Maschinenbau spaß.

Ich konnte das Gerät bisher nur antesten. Negative Eigenschaften sind mir bisher nicht aufgefallen. Für meine Zwecke (NF-Anwendungen) ist das Gerät mehr als ausreichend. Was mir aufgefallen ist: zum Laden k e i n e Schnellladegeräte verwenden. Das Gerät zeigt sonst Symptome wie bei einer defekten USB-Buchse.
