Insulation resistance is vital to designing a safe and effective electrical system. Matching insulation requirements with voltages ensures the most efficient and low cost insulation for a conductor.

Determining this insulation efficiency has never been easier than with the Digital Insulation Tester. With insulation measurements up to 10GΩ with 5 different range settings. This instrument also features a low resistance test function for testing connections between good conductors.

Testing insulation efficiency versus the actual power flowing through the conductor demonstrates how safe a circuit is. This meter has the added ability to measure AC and DC voltage up to 999V. The 380363 Digital Insulation Tester User Manual is attached to this page to answer any further questions.
