Megger MIT420/2 Insulation and Continuity Tester

Overview

The Megger MIT420/2 is a handheld insulation and continuity tester designed for electrical, industrial, automotive, and avionics applications. It provides selectable test voltages of 50V, 100V, 250V, 500V, and 1000V, enabling insulation resistance measurements up to 200 GΩ. Advanced diagnostic functions include Polarization Index (PI), Dielectric Absorption Ratio (DAR), and timed insulation tests with on-board memory for result storage.
