Also picked one of these up.. looks like there is some differences, in regards to the previous models in this thread.
Fx.
* Banana jacks
* 40v to 3665v  (its a screamer)
* 0 to 5mA
* Decimal tolerances (below 1000v / 999.9v)

Model NY35, the older models seems to go from 120v to 2700v and 0 to 3.8mA, and volt reading in full digits.



It is able (to an extent) to light up some of these quite old gas tubes, that I use for spectroscopy (atomic spectra-emission lines).
Though struggles to keep the charge on fx Mercury and Helium .
Neon_ - Mercury_
 

Helium_


The accuracy seems fine.

Prices were around 18$ incl. 25% EUVAT & Delivery (sale, aliexpr.)
Worth noting the listings, claim two LIPO cells, it ain't - just a single..will try to post some pictures from the internals.

But its clearly not useful for such tasks with so little ampere, I tend to use a rigged HV-tester which I can dial up from adj. powerbanks..
