Description
Fluke 1550C Offers
This insulation resistance tester offers digital insulation testing up to 5 kV, making it ideal for testing a wide range of high voltage equipment including switchgear, motors, generators and cables. It can conduct the entire range of test voltages specified in IEEE 43-2000 with a best-in-class, CAT IV 600 V safety rating. With measurement storage and PC interface, it is the perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
