Hi,
I'm on the look for a new multimeter. I currently have a very cheap Uni-T that has served me well for many years, but as I have started to service tube amplifiers, I need something that can withstand higher voltages.
There are several to choose from, but in order for it to properly replace my current DMM, I have a couple of requirements:
Voltage: 1Kv+ (current tube amp I'm working on has 700V AC on the transformer)
Current: 0.1µA (very practical when trying to measure capacitor leakage)
Apart from that, the standard: resistance, voltage, current and diode testing. I already have an LCR meter, so capacitance etc. is of no interest.
My budget is limited, EUR/USD max would be 200-250, but lower is very nice.
Currently, I've found two candidates:
Extech MM750W (https://www.elfadistrelec.no/Web/Downloads/_t/ds/Extech-MM750W-eng_tds.pdf)
Beha Amprobe HEX110-D (https://www.elfadistrelec.no/Web/Downloads/_t/ds/HEX110-D_ger_tds.pdf)
These two couldn't be more different, really. The Extech has all kinds of fancy stuff; True RMS, bluetooth, etc and good specs. I'm not sure if I need true RMS, but whatever.
The Beha Amprobe is way simpler, what-you-see-is-what-you-get. So naturally, I'm wondering, would I regret buying the Extech? I can't find much info from users, except some quality complaints, but that was in 2014.
Beha Amprobe seems to be higher quality, but then again, I don't know.
I've also had a look at Beha-Amprobe HD110C (https://www.elfadistrelec.no/Web/Downloads/_t/ds/HD110C_eng_tds.pdf) - it's more expensive, and no auto range, but can handle 1.5Kv DC - not sure if that's any point, however.
Although these are my current needs, I do envision the new multimeter to live with me for many more years.
Do you have any experience/opinions?

Cant access your links its "protected " or should I say -working in the interests of third parties to deposit cookies etc on me.
So I get a page saying--- you are a bot/power user etc even when I disable two blockers -- not disabling them gets me--- a page saying -- you might have "malware " (excuse ) .

Oh, that's true, they are very suspicious when you disable third party cookies. But if you click the button and do the puzzle, they will let you in 🙂
Sorry the jigsaw puzzle doesn't work as I don't see the the puzzle itself only the one jigsaw piece which I can move but as no puzzle is shown not much use .
As I am constantly on the web and know all the pitfalls of "open browsers " as I used to help those with malware online I am not willing to download a completely insecure browser.
As you are on an audio website I suggest you take into consideration a multimeter with TRUE -RMS ( bigger bandwidth the better).

When connected at the output of an audio amplifier true rms will give you a much more accurate indication of a audio sine wave output in relation to the sine wave input at the input end of an amplifier .
Levels can be checked if the generator is varied between =20Hz and 20kHz while watching the indication on the meter .
I know that's maybe "old fashioned " by modern digital software standards but it can be used for testing any type of sine wave generator either bought or self build and plots can be calculated of bandwidth etc.

Hi,
I strongly recommend You have a look for the Brymen 860 Series, which not only have considerably better specs than the Beha and Amprobe, but are also the only DMMs at the time with CatIV 1000V approval.
I own the 867s myself and could compare it to a Fluke 869 and it beats the Fluke in almost every aspect.
Its a TrueRMS meter that features a great display (Dual display functions, allowing e.g. DC plus a AC-part and vice versa), high resolution of 50.000 counts that can be increased to 500.000(!)counts on some ranges, allowing for µV measurements of e.g. thermocouple elements or precise battery monitoring.
Accuracy is also alot better than the Beha and Amprobe.
AC-wise the 867 reaches to >20kHz, the 869 to >100kHz.
The Crest and Hold functions are very fast, allowing to catch and display very short pulses down to 1ms period.
The build quality is excellent (inserted brass threads and machine screws, sealed housing, etc)
The 867 starts from ~150€, the slightly better in specs 869 costs ~50€ more.
Available from Welectron in Germany, a recommended supplier with very good service.

Thanks! I'm kind of restricted to this supplier, so unless the meters I have found are completely silly, those are pretty much my options.
