Megger MIT410/2 MIT Series Insulation Resistance Testers

Megger MIT410/2 is a second-generation (mk2) insulation and continuity tester from the MIT400 series, designed for electrical and industrial testing applications. As an upgrade to the original MIT410, this model incorporates significant enhancements including a redesigned weatherproof housing, back stand, and improved battery compartment with separate fuse access. The MIT410/2 is distinguished from the base MIT400/2 model by its expanded test voltage selection and advanced diagnostic capabilities, including Polarization Index (PI) and Dielectric Absorption Ratio (DAR) functions.
