Battery Operated (DM Series)

An Insulation Tester is a reliable electrical testing instrument designed to measure insulation resistance in cables, motors, transformers, switchgear, and electrical installations. It applies a high DC test voltage to detect insulation leakage, deterioration, or faults, helping prevent electrical failures and ensuring safety compliance. Built for industrial and maintenance use, insulation testers deliver accurate readings, easy operation, and durable performance in demanding environments.
