Trek 821HH Hand-Held Electrostatic Voltmeter - Manual

® Trek’s Model 821HH Infinitron Hand-Held Electrostatic
Voltmeter represents the next generation of contacting
precision surface voltage measuring instruments, providing
input characteristics far beyond the limits of any currently
available hand-held voltmeter product.
The Model 821HH can easily measure the voltage level of both
conductive and insulative objects and surfaces with virtually
zero charge transfer to the measurement probe. This results in
stable high accuracy voltage measurement capability for ESD-
sensitive devices.
