The Trek Model 520 (±2kV) and Model 523 (±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.

Model 520 is available in two versions. The 520-1 has a digital meter to

display the measured voltage. The 520-2 has an analog output monitor in

addition to the digital display. This analog output monitor can be used to

record the measured voltage or to view it on an oscilloscope.
