Yet Another DMM Indecision Post

KungFuJosh:
I'm leaning towards one of these 3:

Hioki DT4282 $431 on Amazon
Uni-T UT181A $360 on Amazon
EEVblog / Brymen BM786 $165 $173 shipped from Aus, or $199 from Amazon

Diode testing is important to me, and it appears that the Hioki is the best of these. But is it worth the cost difference? The Uni-T looks to be a really good set of specs for the price, but it has the same diode rating as my amprobe, and the BM786 is only slightly better. Would any one of them really be better at testing for leaky diodes?

I don't see anything the OP has written which justifies needing more than 3 plus some fraction digits.

What diode testing specs are you looking at and do you really mean "leaky diodes"?  Leaky would seem to imply you'd want to use the conductance feature, which they all have.  I don't see any obvious difference in normal forward voltage testing as they all seem to specify a 3.0V range.

The BM786 is bandwidth limited to 7kHz and not all that accurate above 1kHz, so if you are working on audio stuff perhaps that matters?

If it was me I would avoid the big-bang-for-buck UNI-T and take the Hioki.  However, I'd check and see exactly what warranty and support you are entitled to if you buy it at a discount from seller 'BUGS BUNNY'.
