Trek 520 Series

Hand-Held Electrostatic Voltmeters for ESD Applications

Advanced Energy's Trek Model 520 (±2 kV) and 523 (±20 kV) hand-held electrostatic voltmeters provide accurate, non-contacting measurements of electrostatic surface voltage. Both are ideal for ESD applications in either ionized or non-ionized environments.

  • Measurement Range 
    • 520: 0 to ±2 kV DC
    • 523: 0 to ±20 kV DC
  • Measurement Accuracy: Better than ±5% of full scale over the recommended probe-to-surface spacing
  • Recommended spacing
    • 520: 5 to 25 mm
    • 523: 30 to 60 mm

Overview

The Trek® 520 voltmeters are not your typical hand-held field-meter. Their measurement technology provides surface voltage measurements that are essentially independent of the sensor probe-to-measured surface spacing.

Trek 520 is available in two versions. The 520-1 has a digital meter to display the measured voltage. The Trek 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. Always use the original grounding cord without any safety resistor; failure to do so will lead to measurement errors.

Benefits

  • Accurately measure surface voltage at a wide range of spacings
  • No need to maintain a fixed spacing

Features

  • Chopper stabilized for drift-free operation in ionized environments
  • NIST-traceable Certificate of Calibration provided with each unit
