Overview

The high-speed Trek® 341B electrostatic voltmeter does not require fixed spacing to maintain DC-stability and high accuracy. It utilizes a field-nulling technique that allows you to measure stationary or moving surfaces. The Trek 341B also uses a patented probe design that eliminates the need for close-tolerance components. This design significantly improves noise and drift in high humidity and wide temperature ranges.

Benefits

  • Measure stationary or moving surfaces
  • Eliminate the need for fixed spacing
  • Benefit from patented probe design that eliminates the need for close tolerance components 
  • Achieve DC stability and high accuracy with field nulling technique
  • Improve noise and drift performance

Features

  • Precision voltage monitor output
  • Use low voltage replica of the measured electrostatic potential for monitoring purposes or  as a feedback signal in a closed loop system
  • Easy-to-read LED display
  • Optional probes offer versatility (order separately)
  • Operate via benchtop, or with optional hardware, in a standard 19-inch rack
  • NIST-traceable Certificate of Calibration provided with each unit

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