High-Speed, DC Stable Noncontacting

Electrostatic Voltmeter

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
bench top operation.
