Megger MIT230 Insulation Tester

The Megger MIT230 Insulation Tester is a compact, reliable solution for insulation and continuity testing. With robust build quality and essential safety features, this tester meets the demands of both industrial and domestic applications. Its intuitive design makes it suitable for routine site maintenance and more complex system diagnostics.

This unit is ideal for testing motors, transformers, switchgear and fixed wiring systems. Whether used in service departments or for field operations, its lightweight profile allows for extended carrying without discomfort. It offers insulation testing at 250 V, 500 V and 1000 V, making it the highest specification model in Megger’s MIT200 series.

Reliable Performance and Safety

The Megger MIT230 Insulation Tester delivers continuity testing above 200 mA with a 0.01 Ω resolution. A live circuit warning with voltage display and test inhibit protects the user. Additionally, automatic discharge ensures residual voltage is safely removed after each test. The display includes both digital and analogue arcs for clarity in varying light conditions.

Practical Design for Everyday Use

This tester supports both alkaline and rechargeable batteries, helping to extend usability across multiple test sessions. It includes an automatic power-down feature after 10 minutes of inactivity. Built-in protective casing and a default voltmeter mode further enhance day-to-day efficiency, making this a trusted tool for engineers and technicians alike.
