IRT-C Insulation resistance tester
626000826Summary
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.
