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 and 1550C are perfect tools for pre-ventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
