Trek Model 800 Infinitron®
Ultra-High Impedance Voltmeter

  • Measurement Range:
  • Measurement Accuracy:
  • Speed of Response:
  • Input Characteristics:

  • 0 to ±100 V DC or peak AC
    Better than 0.1% of full scale
    (voltage monitor output)
    Less than 3.5 ms for a 100 V input step
    Resistance greater than 1 x 1016Ω
    Capacitance less than 1 x 10-15F

The ±100 V Trek Model 800 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 800 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.

Typical Applications Include
  • Accurate reading of electrostatic voltage levels associated with ESD sensitive components, circuits and surfaces
Features and Benefits
  • Two voltage monitor outputs scale factors at 20:1 and 1:1
  • 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
  • Easy-to-read LED display
  • Designed to be operated on a bench top
