Máy đo điện áp tĩnh điện Trek 368A
The Trek 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 Model 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.
