TREK electrostatic voltmeters 876 / 884

Electrostatic voltmeters for accurate non-contacting measurements of the electrostatic surface voltage for ESD applications in ionized or non-ionized environments.

PRODUCT HIGHLIGHTS

Accurately measures surface voltage at a wide range of spacings
No need to maintain a fixed spacing
Chopper stabilized for drift-free operation in ionized environments
NIST-traceable Certificate of Calibration provided with each unit

APPLICATIONS

Measurement of electrostatic surface charge build up
Manufacturing processes
Electronic assembly testing
Semiconductor material testing
Dissipative material testing
Automotive electronics testing
ESD Auditing and troubleshooting

The Trek^® 876 (±2kV) and Trek 884 (±20kV) hand held electrostatic voltmeters provide accurate, noncontacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments. These two voltmeters utilize a measurement technique that overcomes the disadvantage of the typical hand held field-meter by providing surface voltage measurements which are essentially independent of the sensor probe-to-measured surface spacing.
