Extended Range Insulation Resistance Testers

  • Multiple test voltages
  • Guard terminal to eliminate surface leakage current
  • Voltage indicating range

This Insulation Resistance Tester is the ideal instrument when high ranges are needed for measuring insulation resistance. It provides excellent test voltage regulation and an external guard terminal to eliminate surface leakage current from the measurement.

The instrument is all electronic; it generates a regulated dc high voltage and use low-zero-drift, high-accuracy circuits, with high current sensitivity. Designed for portability, it is enclosed in a molded, impact-resistance, flame-retardant case.

Please note: the 210600 unit has been discontinued.
