TREK, INC. is a leading manufacturer and supplier of precision
electrostatic measurement instruments for ESD applications.
Accurate measurements are important for identifying sources
of charge generation, and for verifying the effectiveness of
ESD countermeasures that are employed in ESD control
programs.

Since 1983, TREK, INC. has shipped more than half-a-million
sets of embedded electrostatic monitors to manufacturing
companies around the world. The low-profile, PC board
design makes them ideal for continuous monitoring of
electrostatic voltage in automated processes. A precision
voltage divider output provides a low-voltage replica of the
measured electrostatic voltage for interface to a facilities
monitoring system.

Trek’s reputation for quality and reliability has been highly
respected for more than 25 years. Trek noncontacting
electrostatic monitors are designed to provide accurate, drift-
free, high-speed and low noise measurements.

Trek electrostatic monitors accomplish voltage measurements
without physical contact to the measure surface by making use
of a chopper stablized, field-nulling technique which maintains
DC stability and high accuracy over wide probe-to-surface
variations. This technique assures no loading of the voltage
and permits accurate measurements without the need to
establish a fixed probe spacing.
