The Trek Infinitron 821HH handheld electrostatic voltmeter from Advanced Energy provides next-generation contacting-precision, surface-voltage measuring capabilities.
The Trek® Infinitron® 821HH hand-held electrostatic voltmeter offers far-reaching input characteristics, data graphing capabilities, and easy-to-read LCD. It can easily measure the voltage level of conductive and insulative objects surfaces with virtually zero charge transfer to the measurement probe. And this makes it ideal for use in ESD-sensitive environments.
