Vintage sensitive research microamperes meter nice
Still cleaning out the basement!
This is a vintage Sensitive Research Microamperes meter. The dial reads from 0 to 30 and 0 to 100. The knob on the bottom adjusts from 10 to 1000. IT must be a multiplier. It says it is a University Model. There is a calibration sticker on it that says 3.27.3 and 6.30.3 but I can't imagine this dates from 1927 and 1930, unless I'm way off. It says the calibration frequency was 90D.
The unit has been sitting in my basement for probably 10 years. It's untested but looks pretty darn solid.
