Fluke 1550C Insulation Resistance Tester
The Fluke 1550C insulation resistance tester 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. It’s Fluke Connect compatible with ShareLive video so you can stay in contact with your entire team without leaving the field.
With measurement storage and PC interface, the Fluke 1550C insulation resistance tester is the perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur. The FlukeView Forms Basic software (included) allows for further analysis on a PC. Other features of the 1550C include selectable test voltages in 50V steps, automatic calculation of Delectric Absorption (DAR) and Polarization Index (PI) and a guard system that eliminates the effect of surface leakage current on high-resistance measurement.
A large digital/analog LCD display makes viewing results easy. The measurements, stored in up to 99 memory locations, feature a unique, user-defined, label per location for easy recall. A warning function alerts the user that the line voltage is present and gives the voltage reading up to 600 VAC or VDC, for increased user safety.
