Fluke Digital Insulation Resistance Tester - 5 KV

Product Information: Fluke 1550C Digital Insulation Resistance Tester is the redesigned insulation resistance tester. It offers digital insulation testing up to 5kV, 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 are perfect tools for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
