Fluke 1507 Insulation Resistance Tester

The Fluke 1507 Insulation Resistance Tester is a highly reliable and feature-rich tool designed to perform advanced insulation resistance testing in industrial, commercial, and residential environments. With its compact, lightweight, and portable design, it is perfect for contractors, electricians, and maintenance professionals who need accurate results in the field.

This insulation tester supports five test voltages — 50V, 100V, 250V, 500V, and 1000V — allowing users to test a wide range of equipment and systems. It measures insulation resistance from 0.01 MΩ to 10 GΩ, making it suitable for troubleshooting motors, transformers, wiring, and electrical installations. The device automatically calculates Polarization Index (PI) and Dielectric Absorption Ratio (DAR), providing valuable insights into insulation quality and degradation over time.

For enhanced safety, the Fluke 1507 features live circuit detection that prevents testing when voltages above 30V are present and includes auto-discharge capability to safely release stored capacitive energy. Its Compare (Pass/Fail) function simplifies repetitive testing, while the remote test probe allows for convenient operation in hard-to-reach areas.

The tester also measures AC/DC voltage up to 600V, resistance up to 20 kΩ, and provides low-ohms earth-bond continuity testing using a 200 mA current. With its CAT IV 600V safety rating, rugged construction, and IP40 protection, the Fluke 1507 is built for demanding industrial environments. It offers up to 1000 insulation tests on a single set of batteries, ensuring long-lasting performance.

Whether used for commissioning, preventive maintenance, or troubleshooting, the Fluke 1507 delivers precision, durability, and ease of use — making it an essential tool for professional electricians and engineers.
