Electrostatic Voltmeters

Non-Contacting Electrostatic Voltmeters

Trek’s novel non-contacting voltmeter designs achieve high accuracy measurements that are virtually insensitive to variations in probe-to-surface distances, and prevent arc-over between the probe and measured surface. This is ideal for applications where surface contact must be avoided.

Contacting Electrostatic Voltmeters

Trek's Infinitron® line offers a breakthrough in the world of electrostatic voltmeters. This ultra-high impedance contacting voltmeter technology makes it possible to do highly accurate contacting measurements with virtually no charge transfer. This contrasts with other contacting measurement technologies that transfer charge upon contact, thereby compromising the electrical condition of the surface being measured.
