Trek's electrostatic voltmeters accurately measure surface potential (voltage) on materials. Trek's non-contacting technology avoids the problems of arc over between the probe and measured surface, delivering a high accuracy measurement that is virtually insensitive to variations in probe-to-surface distances.
Static charge accumulation presents a serious problem in many sensitive manufacturing processes. Static charges are often dissipated in uncontrolled ways that can damage product or cause process equipment failures. Trek's electrostatic measurement technologies address that need and provide desirable alternatives to fieldmeter technology and its drawbacks.
