• Easy to read 3% Digit LED display • Superb noise and drift performance • Miniature probes • Precision voltage monitor provides low-voltage replica of measured voltage • Up to four independent channels in full rack mountable configuration Model 368A High-Speed, DC Stable Noncontacting Electrostatic Voltmeter • Noncontacting measurement range 0 to ±2 kV or peak AC • Speed of Response less than 200 ms for a 1 kV step • Accuracy better than 0.1% of full scale Trek’s Model 368A High-Speed Electrostatic Voltmeter provides precision noncontacting measurement of the surface voltages associated with electrostatic imaging processes as employed by the electrophotographic reproduction and laser printing industries. Highly accurate electrostatic voltage measurements are also associated with applications such as photoreceptor research and semiconductor processing. The 368A is used in research and development applications and to measure electrostatic potentials on objects or surfaces such as polymer, film, fabric, and paper. The miniature sensor probes utilize a patented dual chopper design. This design provides high-speed, DC stable measurements with exceptional low noise and drift performance in wide temperature range conditions, under high humidity, and even in the presence of contaminating particulates. Sensor probe options include standard or high-temperature probes with either an end-viewing or side-viewing orientation. The voltage of moving or stationary surfaces can be easily measured with high accuracy over a wide range of sensor probe to measured surface spacings. The noncontacting measurement ensures that no charge transfer will take place to modify or destroy the actual data. A user selectable dual range precision voltage monitor provides a low-voltage replica of the measured electrostatic voltage for external monitoring purposes or for use as a feedback signal in a closed loop control system. Rack mount options are available to permit up to four independent measurement channels in a standard full rack or for compact • C€ Compliant bench top operation.
