Old analog millimeter milliamperes DC just for you
Vintage & collectibles, Antique, 50 to 75 years
This vintage amateur has five settings maxed at 15 milliamps 3 milliamps 1.5 milliamps .75 milliamps and .3 milliamps. I have tested the 1.5 milliamp setting and found that it works. I do not know if it's properly calibrated. This was manufactured by sensitive research instrument Corporation. Model UT. Serial number 601504. It has to contacts as shown in the photo but one of them is missing its insulating knob. This unit is made of Bakelite and is rather heavy for its size. It's about 4 in by 4 in by 2 in.
