©2023 Advanced Energy Industries, Inc. 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. 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
