I've got an electrochemical voltage reference cell. Its an Eppley Laboratories M51316 with a rated voltage of 1.0913V +/-0.1%. I've Googled to no avail.
1) Does anyone know what the chemistry of this thing is?2) How many coulombs of charge can one expect to get out of this?
3) There's a small gas bubble near the cathode. From normal use or excessive current draw?This was a part of an old Fluke 801 DC voltmeter (not worth saving). But the cell appears to be OK and will make a decent calibration check for my shop junk.
