Is NON-CONTACT VOLTAGE feature worth it?
donescamillo:
Hi,
Silly question, but still have to ask it:
for home and hobbyist usage, is it worth choosing Brymen 829, which has NON-CONTACT VOLTAGE detection (which I guess comes in handy) over Brymen 869s, which is more precise, has more features but no NON-CONTACT VOLTAGE detection?
I currently have AstroAi M6KOR, but I have not really pushed it hard and I think is not as robust as the Brymens.

How often?
It can be bought as a separate very cheap device, if you really need it. The 869s is a great DMM (but it sure could use a facelifting refreshment -- it's an older platform) for everything else.

I don't have any specific experience with the Brymen but many measuring devices, typically from China, have some sort of NCV detection capability added on and they're anything from poor to near-useless. Given that you're using this to try and detect the presence of lethal voltages, I'd buy a separate device for this purpose and then test it to make sure that it will actually warn you of lethal voltages. Again, most of the cheap Chinese ones aren't something I'd want to rely on for warnings.
jonpaul:
if mains or HV safety is involved get a Fluke or Miller hot stick electricians volt probe.
We use only Fluke DVM, eg 87V.
Dont trust yoru life to China DVM

I wouldn't trust *any* non-contact detector when it comes to safety considerations. NCV is just a convenient preliminary indicator, that's it.
