Evaluate the trends, eliminate the doubt
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.

• Test voltages to up 5 kV
• 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
