©2020 Advanced Energy Industries, Inc. The Trek® 520 (±2 kV) and Trek 523 (±20kV) hand held electrostatic voltmeters that 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. The Trek 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. 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
