Trek Infinitron 821HH


Contacting Hand-Held Electrostatic Voltmeter

The Trek® Infinitron® 821HH hand-held electrostatic voltmeter offers far-reaching input characteristics, data graphing capabilities, and easy-to-read LCD. It can easily measure the voltage level of conductive and insulative objects surfaces with virtually zero charge transfer to the measurement probe. And this enables stable, highly accurate voltage measurements for ESD-sensitive devices.


  • No current flow at time-of-contact, probe tip assumes the voltage level object’s surface
  • Voltage monitor output provides low voltage replica of the measured voltage
  • Less than 500 µS for an input step change of 1 kV
  • NIST-traceable calibration certificate provided with each unit
  • Easy-to-read LED display


  • Use in semiconductor, LED, MR head sensor, and other ESD sensitive applications
  • Operate using a battery or a line
  • Easily record voltage, temperature, and humidity
  • Set automatic shutoff for 5, 10, or 15 minutes


Operational temperature range (°C): 15 to 35
Measurement Range: 0 to ±2000 V
Measurement Accuracy (%): ±1%
