Contact Voltmeter

CVM-780 - Prostat Corporation (PSC)

The CVM-780 Contact VoltmeterTM combines the ease of use of a digital voltmeter with the high input impedance and low input capacitance of a true electrostatic voltmeter in a small, portable, battery operated package.
Being a true electrostatic voltmeter, not a field meter means that it reads real voltage, without confusing it with electrostatic field strength, which can be distinctly different.
