The Trek Model 876 (±2kV) and Model 884 (±20kV) Hand-Held Electrostatic Voltmeters provide accurate, non contacting 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.

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
