Perform tests, collect data wirelessly and from a safe distance
The Fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kV, making it ideal for testing high voltage equipment including switchgear, motors, generators and cables.
Data collection is easy using the Fluke Connect® wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. The 1555 insulation tester can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, warranty and CAT IV 600 V safety rating.
