Trek 370-1-L-CE High Speed Electrostatic Voltmeter

Description:

The TREK 370-1-L-CE high speed electrostatic voltmeter is used in electrostatic measurement systems to provide precision non-contact measurement of surface voltages up to ±3 kV DC or peak AC. Commonly installed in semiconductor manufacturing equipment, ESD testing stations, electrophotographic systems, research laboratories, and industrial production lines where accurate electrostatic potential monitoring is required. Maintenance teams, test engineers, and system integrators use the 370-1-L-CE for repair, retrofit, laboratory testing, equipment upgrades, and replacement of electrostatic measurement instruments.

Applications:

The TREK 370-1-L-CE high speed electrostatic voltmeter is commonly used in semiconductor fabrication, static charge monitoring, materials research, film and plastics manufacturing, and automated test equipment where precise non-contact voltage measurements are essential. Its electrostatic field-nulling technology, automatic gain control, and high-speed response enable accurate measurements of stationary and moving surfaces without requiring fixed probe spacing.
