Fluke 1503/1507 Insulation Resistance Tester – 1507

The Fluke 1507 Insulation Resistance Tester is your go-to tool for advanced insulation testing in industrial and electrical environments. Designed for efficiency, portability, and durability, the Fluke 1507 makes it easy to perform insulation checks during troubleshooting, commissioning, or preventative maintenance.

With a wide range of test voltages and resistance measurements from 0.01 MΩ to 10 GΩ, this compact handheld tester is ideal for professionals demanding versatility and safety. It features a live circuit detection system that prevents insulation testing when voltage above 30 V is present, as well as auto-discharge of capacitive voltage for enhanced user protection. The included remote test probe simplifies operations in tight or repetitive testing scenarios.

Backed by Fluke’s reputation for rugged, reliable tools, the 1507 comes equipped with essential accessories and a one-year warranty—making it an excellent value for both field and bench use.
