Insulation tester PCE-IT100
For insulation resistance up to 4000 MΩ / CAT III 1000V / Easy handling / Simple or continuous measurement / Maximum and minimum value function
For insulation resistance up to 4000 MΩ / CAT III 1000V / Easy handling / Simple or continuous measurement / Maximum and minimum value function
The PCE-IT100 insulation tester detects insulation resistances up to 4000 MΩ with auxiliary voltages of 125V, 250V, 500V, and 1000V. Additionally, it is used to measure resistances up to 400 Ω and alternating and direct voltage. A continuity tester with an audible signal is also part of the insulation tester's equipment. The tester features a data hold function as well as a function to record the maximum and minimum values.
The large digits, backlit display, and ease of use make the PCE-IT 100 ideal for demanding environments with limited lighting. The insulation tester comes with a set of test leads with test probes, a test lead with crocodile clip, and 6 batteries.
Compliance limits for insulation measurement
