IRT-C Insulation resistance tester

626000826
Summary
The insulation resistance tester IRT-C is engineered for accurate measuring of LV-installations and appliances according the EN 61157 regulation. The tester has been developed to measure voltage and continuity.

Also insulation resistance of high sensitive parts and even heavy machines or ground cables can be measured easily with the four different test voltages.
 

Measurements

  • Insulation resistance with a test voltage of 100 VDC
  • Insulation resistance with a test voltage of 250 VDC
  • Insulation resistance with a test voltage of 500 VDC
  • Insulation resistance with a test voltage of 1000 VDC
  • Partial resistance of earth connection (200 mA)
  • Voltage
