2KV High Impedance contacting voltmeter/Non-contacting Voltmeter

  • Product No:820
  • Manufacturer:Trek, Inc.

The ±2 kV Trek Model 820 Infinitron Voltmeter may be used in either contacting or non-contacting mode to acquire precision surface voltage measurements. It is especially beneficial when used with applications that demand infinitely high loading impedance levels far beyond the reach of currently available high impedance voltmeter instruments. The Model 820 comes with a guarantee of virtually no modification of the object being measured. This allows the instrument to indicate, with high precision, the voltage level of both conductive and insulative objects and surfaces.

Voltage monitor output scale factor at 1/200

Probe electrode may be easily replaced with other sensor tips

Monitor provides a low voltage replica of the measured electrostatic potential for monitoring purposes or for use as a feedback signal in a closed loop system

Digital Enable allows an external device to turn ON/OFF the internal HV power supply

Easy-to-read LED display

Designed to be operated on a bench top
