Hantek 2C42 Digital Oscilloscope Multimeter USB Portable 2 Channels 40MHz 250MSa/s Multifunction Tester

Me gusta bastante, cumple su función como DMM y oscilo. Lo uso para car audio y me da lo que necesito.

This looked a good item however the one I was sent had the connector missing from the kit and it was refunded. They could not send out a replacement or the part which was missing however, it did look like a good item for the price.

Very happy with this unit. Works well.

First the nits to pick ... It comes with a wall plug for USB, but it is European or Asian format plug, so unless you want to use an adapter it doesn't work. It appears that it will charge on a normal USB supply, but at only 1amp, it has to take longer. Also, it only comes with probe and even that one is a cheapo alligator clip probe. It would have been a nice touch to include this probe in addition to a pair of real 'scope probes, but as the only one, I wasn't impressed. Lastly, the settings are not obvious or intuitive, mostly because the menus are a little hokey and the display doesn't make complete use of units ... so the time, for example, says 10msec ... but it doesn't confirm that this is per division or for the whole screen (it is /div). After I got past these issues, I found a 'scope that actually works and seems to work pretty well ... it isn't as easy to use as my benchtop, but it is a LOT more convenient to carry. I think that I will leave a second pair of reading glasses in the case as the screen isn't all that easy to read, but the information IS there and for this price, I am not going to complain.

I bought this because I got tired of bringing my multimeter home from work, and I decided why not an oscilloscope as well. The multimeter portion is a little slow at reading but is dead on accurate. The oscilloscope portion is very accurate, but it can be confusing going through the menu's and the screen is small with few presets, this is not a problem for someone experienced with a scope who ignores presets anyways but would probably confuse newer scope users. It is not a professional scope, it works and works well but if you want a professional one buy a professional one, hantek sells professional scopes, as does nearly every other scope maker. I bought this so I did not have to bring my autel scope and scanner home or my fluke multimeter to mess with my own vehicles or my friends vehicles, it is great for sidework and great for smaller projects for users who are patient, but if you want automotive shop or electrician tech efficiency you need to pony up for a higher end model from hantek or the other makers. So far I have checked ac ripple on an alternator and done injector and coil waveforms with attenuators. One big gripe is the lack of the 20:1 preset, as those are the attenuators sold by hantek, but they start at 10:1 and skip 20:1, not an issue for someone who can divide but again not a newbie friendly feature.
