The Fluke 1555 Insulation Resistance Tester, offers digital insulation testing up to 10kV, making them ideal for testing a wide range of high voltage equipment including switch gear, motors, generators and cables. Fluke insulation testers can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, 3 year warranty and CAT IV 600 V safety rating. With measurement storage and PC interface, the Fluke 1555 is a perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.

• Test voltages up to 10 kV provides solutions for all applications
