Trek Infinitron 820 Series


Contacting or Non-Contacting High Impedance Voltmeter

The ±2 kV Trek® Infinitron® 820 voltmeter can be used in contacting or non-contacting mode to acquire precision surface voltage measurements. Virtually no object or surface modifications are required. This allows the Trek® Infinitron® 820 to precisely indicate the voltage level of both conductive and insulative objects and surfaces.


  • Voltage monitor output scale factor at 1/200
  • NIST-traceable calibration certificate provided with each unit
  • Easy-to-read LED display
  • On-benchtop design
  • Reset button


  • Use low voltage replica of the measured electrostatic potential for monitoring purposes or as a feedback signal in a closed-loop system
  • Use in either contacting or non-contacting mode
  • Easily replace the probe electrode with other sensor tips
  • Turn internal HV power supply on or off via external device
  • Quickly and easily transfer data via USB port
