Coulomb meter
Coulomb meter
I am looking for a meter that will allow me measure coulombs in a system running at 20-200V DC, 0-10A. Is there one available?

Re: Coulomb meter
Keithley Coulombmeters can measure charge from 10fC to 20uC.
Model 6514 and 6517B are the current models that can do this.
The maximum input on these units is 250VDC.

Re: Coulomb meter
What I am looking to get out is coulombs, measured by integrating amp-sec. The voltage would be constant, say 100V DC, and the current will initially spike to perhaps 10 amps, then rapidly decrease towards zero. This is for an electrophoretic coating process. Coating thickness will be directly proportional to coulombs, and the process could be controlled by having the power cut off after a specific number of coulombs have been recorded. How would I set up the instrument to measure this?
