TREK 344-3-G Electrostatic Voltmeter

The TREK 344-3-G Electrostatic Voltmeter provides precise non-contact surface voltage measurements from 0 to ±2 kV with an accuracy better than ±0.05% of full scale. Its non-contact electrostatic field-nulling technology maintains high accuracy as probe-to-surface distance changes, making it suitable for stationary and moving targets in semiconductor manufacturing equipment, electrophotographic systems, research laboratories, static control stations, and industrial production lines where accurate electrostatic potential monitoring is required. Key specifications include a 3½-digit LED display, Buffered BNC output (1/100 scale), and universal power input of 100/115/230 VAC, 50/60 Hz (factory configured). This instrument is commonly used by maintenance teams, test engineers, and system integrators for repair, retrofit, laboratory testing, equipment upgrades, and replacement of electrostatic measurement instruments.
