Insulation Tester FLUKE 1550C

Fluke 1555C insulation tester for high voltage equipment testing / resistance measurement up to 1 TΩ

The FLUKE 1555C insulation tester is suitable for measuring voltages up to 10 kV, making it ideal for testing a wide variety of high voltage equipment including switches, motors, generators, and cables. The insulation tester meets CAT IV 600 V safety specifications, providing high safety for the user. The acquired data can be stored in internal memory or transferred to a PC via the interface. The large display allows for easy reading of values. This insulation tester is the ideal instrument for carrying out predictive or preventive maintenance, and is designed to identify potential equipment failures before they occur.

Electrical specifications

The accuracy of the tester has been specified for 1 year once calibrated at operating temperatures between 0 °C and 35 °C. For operating temperatures outside the range (from -20 °C to 0 °C and from 35 °C to 50 °C), add ±25% per °C, except in the bands with 20%, where you should add ±1% per °C.
