Fluke 1550C/Kit Insulation Resistance Tester Kit

The new Fluke 1550C/Kit insulation resistance tester offers digital insulation testing up to 10 kV, making it ideal for testing a wide range of high voltage equipment including switchgear, 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 1550C/Kit is a perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
