MI-5500e General Purpose Insulation Tester

The MI‑5500e is a general-purpose, high-voltage insulation resistance tester, designed for portability and field use. Capable of measuring insulation resistances up to 10,000,000 MΩ (10 TΩ), it supports four selectable test voltages: 500 V, 1 kV, 2.5 kV, and 5 kV.

This rugged, analog tester is ideal for professionals who value the visual response and diagnostic cues provided by a moving pointer — something digital screens can’t always replicate. With its large analog scale, easy-to-use interface, and cost-effective design, the MI‑5500e is built for high-reliability measurements in demanding conditions.
