7.5 digit bench DMMs comparison

(1/13) > >>

Dragony:
Hello,

I want to purchase a good 7.5 digit DMM for my bench. The problem is that for a hobbyist the price tags of this devices make it impossible to just buy and hope you got the right one. Furthermore a hobbyist won't look into 8.5 DMMs, since, well, hobbyist, you know.

I am surprised I were unable to find a good comparison between just 7.5 DMMs combined with price and year of release. When I decide to spend $2000-$4000 for a bench DMM, for many years to come I want to say "thats the best thing I can get for the money spent." Of course, who doesn't?

As far as I have found out so far the only available rather recently released 7.5 DMMS are Keithley DMM7510 and Keysight 34470A. Do you know any other ones?

Vgkid:
Your other option for 7.5 digit dmms are: datron 1071, solartron 7075, solartron 7071, keithley 2001, hp 3457. There are most likely some from advantest, and prema.

Dragony:
I found a suspiciously good comparison of DMM7510 vs 34470A. The DMM7510 is the clear winner. Can someone say if its plausible, or is it Keithley Propaganda?

Kjelt:
Why do you need/want 7,5 digits and have you looked at the cost for calibration each and every year?

zlymex:
The Advantest one is R6871, the Prema one is 5017. There are also another Datron one 1081, another Keysight 34420A, another Solartron 7061, and 8071 from Transmille. I am a hobbyist and I got three 8.5 digit DMMs(1281, 3458A and R6581T)
