Trek 347


Non-Contacting, Economical Electrostatic Voltmeter for Surface Voltage Measurements ±3 kV DC or Peak AC

The Trek® 347 non-contacting electrostatic voltmeter provides precision and value for surface voltage measurements in the range of ±3 kV DC or peak AC. Its field-nulling technique allows you to accurately measure stationary or moving surfaces. And its patented probe design enhances noise and drift performance in the presence of contaminating particulate or under conditions of high humidity and / or wide temperature ranges.


  • Precision voltage monitor output
  • Low voltage replica of measured electrostatic potential provided for monitoring purposes or use as a feedback signal in a closed-loop system
  • Easy-to-read LED display
