Fluke 1555 Insulation Resistance Tester

The Fluke 1555 insulation resistance tester allows for a digital check of insulation up to 10 kV, making them ideal for a wide range of high-voltage equipment, such as circuit breakers, motors, generators, and cables.

Fluke insulation testers can now check the full range of test voltages specified in IEEE 43-2000 with a three-year warranty, the best in its class, and CAT IV 600 V safety category. Thanks to measurement storage and the PC interface, the Fluke 1555 is the ideal instrument for carrying out predictive or preventive maintenance, and they are designed to identify potential equipment failures before they occur.
