Trek 323


Highly Sensitive, Versatile Electrostatic Voltmeter, Measure 0 to ±100 V

The Trek® 323 is a versatile instrument. It is used in various electrostatic applications, including materials evaluation, electret studies, charge accumulation on disk drive assemblies, and other extremely sensitive ESD components. The Trek® 323 features adjustments to compensate for many sensitive testing conditions. The response speed control adjusts the speed/noise tradeoff of the AC response. While the drift/spacing null adjustment minimizes the variation in zero-offset voltages as the probe-to-test surface spacing changes. 


  • Sensitivity: 5 mV
  • Drift spacing/null adjustment
  • Response speed control
  • Additional probes available


  • Utilize low impedance probe sensor that assures high accuracy in high humidity and contaminated environments (e.g. airborne dust, toner, ions, and chemicals)
  • Monitor detected output voltage through a 1:1 voltage monitor output and a switch-selectable scale of 10:1 or 20:1 voltage monitor output
  • Use with various shaped probes (e.g. round, square)


動作温度範囲 (°C): 0 to 40
