The Fluke 1550B is a digital insulation tester capable of testing switchgear, motors, generators and cables at up to
5000 V DC. It can be used for a wide range of tests: from simple spot checks to timed tests and breakdown tests.
Measurement storage and PC interface software make it ideal for preventive maintenance. Heavy-duty leads,
probes and alligator clips fit in the custom carrying case, for a rugged field testing kit.
