Feature: 1. The insulation resistance tester is compact, rugged, reliable, and easy to use. 2. Repetitive or hard-to-reach testing is easy with the remote test probe. 3. Live circuit detection prevents insulation test if voltage > 30 V is detected for added user protection. 4. CAT IV 600 V overvoltage category rating for added user protection 5. The large backlight display screen make it easy to read measurements. 6. Remote probe, test leads, probes and alligator clips included with each tester 7. With its multiple test voltages, the tester is ideal for many troubleshooting, commissioning, and preventative maintenance applications.
