The Trek Model 876 (±2kV) and Model 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-tomeasured surface spacing
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
