Fluke 1503 Insulation Tester

This rugged, compact insulation resistance tester is designed for professional use by residential and commercial electricians. It measures insulation resistance from 0.01 MΩ to 2000 MΩ and supports test voltages of 500 V and 1000 V. The device also measures resistance from 0.01 Ω to 20.00 kΩ and includes live circuit detection to prevent insulation testing if voltage exceeds 30 V. Additional features include a remote probe, safety features, a backlit LCD, and power from four AA batteries. It is CAT IV 600V rated and RoHS compliant, making it suitable for a range of electrical diagnostics in demanding environments.
