The Trek Model P0865 is a DC stable, precision electrostatic
voltmeter for making noncontacting surface voltage
measurements in the range of 0 to ±10 kV DC or peak AC.

Research and industrial applications include charge
accumulation monitoring of the LCD production processes,
monitoring surface potentials in the electrostatic painting
process, research and development in the electrophotographic
process, and measuring electrostatic potentials on polymers,
rubber, fabrics, and paper.

The Model P0865 employs a field-nulling technique for
noncontacting voltage measurement that achieves DC stability
and high accuracy even if the probe-to-surface spacing changes.
This permits measurements of either stationary or moving
surfaces without the need to establish fixed spacing to maintain
accuracy.

The Model P0865 patented probe design eliminates the need for
close tolerance components. This significantly improves noise
and drift performance, both in the presence of contaminating
particulates and under conditions of high humidity and wide
temperature ranges.

A precision voltage monitor provides a low-voltage replica of the
measured electrostatic potential for monitoring purposes, or for
use as a feedback signal in a closed-loop system.

The Model 3450 probe assembly includes a sensitive electrode
and preamplifier, which is driven to the same potential as the
measured value to eliminate arcing there between. A three (3)
meter cable permits remote probe positioning. The Model
P0865 can be operated on a bench top or, with optional
hardware, in a standard 19-inch rack.
