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-to-measured surface spacing.

Always use the original grounding cord without any safety resistor; failure to do so will lead to measurement errors.

Typical Applications Include
  • Measurement of electrostatic surface charge build up
  • Manufacturing processes
  • Electronic assembly testing
  • Semiconductor material testing
  • Dissipative material testing
  • Automotive electronics testing
  • ESD Auditing and troubleshooting
Features and Benefits
  • 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
