Overview

The Trek® 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.

Benefits

  • Easily use for automated or computer-controlled systems
  • Operate on a benchtop, or with optional hardware, in a standard 19-inch rack
  • Utilize Digital Enable to turn the internal HV power supply on or off from an external device
  • Improve drift and noise performance
  • Choose from a large selection of optional probes (order separately)

Features

  • 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
  • CE compliant

Select specifications are shown below. Please see product data sheet for additional specifications.
