Fluke 1503 Insulation Resistance Tester (500 V / 1000 V, 2000 MΩ, CAT IV 600 V)

HIGHLIGHTS:

The Fluke 1503 Insulation Resistance Tester is a rugged, compact, and reliable diagnostic tool engineered for electricians performing residential and commercial insulation testing. Designed to handle essential insulation measurement tasks with efficiency, it offers a measurement range from 0.01 MΩ to 2000 MΩ, ensuring accurate evaluation of insulation integrity across a wide range of applications.

Equipped with two insulation test voltages (500 V and 1000 V), the Fluke 1503 delivers flexibility for standard testing requirements. Its built-in live circuit detection enhances safety by preventing insulation tests when voltage above 30 V is detected. The tester also features auto-discharge functionality, ensuring capacitive voltage is safely discharged after testing.

Beyond insulation testing, this versatile unit measures AC/DC voltage up to 600 V and low-resistance continuity (earth-bond) with high accuracy. A large backlit display provides clear readings in all lighting conditions, while the remote probe capability streamlines repetitive or hard-to-reach testing tasks.

Built to withstand demanding environments, the Fluke 1503 features a CAT IV 600 V safety rating, durable construction, and a compact ergonomic design. Powered by four AA batteries, it delivers up to 1000 insulation tests per battery set, making it a dependable choice for field professionals.
