Overview

The Trek® 542A electrostatic voltmeter (pictured with the Model 542P-S probe) is configured with a miniature electrostatic field chopper probe. The probe can be remotely located and easily positioned within process equipment to provide highly accurate, non-contacting, DC-stable, spacing-independent voltage measurements in either ionized or non-ionized environments. The unit's 20 x 4 alphanumeric LCD screen displays the present measured voltage, positive and negative peak voltage values, and additional menu information.

Benefits

  • Enable drift-free measurements
  • Benefit from visual and audible alarms that activate when preset voltage-threshold levels are reached
  • Remotely locate or easily position miniature field chopper probe
  • Use in ionized or non-ionized environments
  • Take spacing-independent voltage measurements

 

 

Features

  • Chopper probe is DC-stable with or without incident airflow
  • Analog voltage monitor output
  • USB and RS-232 serial ports
  • NIST-traceable calibration certificate provided with each unit
  • Walking test adapter kit available

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