    The Fluke 1550C insulation resistance tester offers digital insulation testing up to 5 kV, making them 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 is the perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.

  • Features include:

    • Test voltages to up 5 kV and save time by trending on the spot only with Fluke Connect™
    • CAT III 1000 V, CAT IV 600 V safety rating
    • Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety
    • Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V
    • Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
    • Long battery life gives the user over 750 tests between charges
    • Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
    • Guard system eliminates the effect of surface leakage current on high-resistance measurements
    • Large digital/analog LCD for easy viewing
    • Capacitance and leakage current measurement
    • Ramp function for breakdown testing
    • Resistance measurements up to 2 TΩ
    • Timer settings up to 99 minutes for timed tests
    • 3-year warranty
  • Electrical Specifications
    The tester's accuracy is specified for one year after calibration at operating temperatures of 0°C to 35°C. For operating temperatures outside the range (-20°C to 0°C and 35°C to 50°C), add ± .25% per °C, except on the 20% bands add ± 1% per °C.
