High Voltage Probes for Very Low Current Power Supply Voltage Measurement
to 120kV, such as Electrostatic Paint Spray Applications...



  • Up to 120kV DC, 85kV AC RMS 50/60 Hz or more.
  • 10,000 megohms or more HV input resistance.
  • Usable with any digital meter of 10 megohms input.
  • Higher voltage, higher resistance, lower current also available.
  • Available with insulated handle meeting OSHA recommendations.
  • Only draws 12 microamps at 120kV DC, minimizing power supply loading.
  • 1000/1 ratio with 10 megohm output load, 10,000/1 ratio with 1 megohm output load.
  • Available with 0.5% or better DC accuracy when supplied complete with meter or calibrated with user’s digital meter.
