Megger MIT1025 10 kV Insulation Resistance Tester with HV Lead Set Advanced IR, DAR, PI, DD, SV, Ramp Diagnostics

Megger MIT1025 High-Voltage 10 kV Insulation Testing Performance

The Megger MIT1025 is a fully featured 10 kV insulation resistance tester engineered for high-voltage asset inspection, long-term condition trending, and diagnostic insulation analysis. Built on Megger’s dual-case design with CAT IV 600 V safety rating, the MIT1025 delivers laboratory-grade measurement stability in field environments where reliability, noise rejection, and operator safety are essential. Its 20 TΩ maximum resistance capability, rapid-charge Li-ion battery, and intuitive dual-rotary interface make it a preferred tool for utilities, OEMs, service contractors, and industrial reliability teams.

Why It Helps

With selectable IR, timed IR, DAR, PI, Dielectric Discharge (DD), Stepped Voltage (SV), and ramp test modes, the MIT1025 provides deep visibility into insulation performance across cables, transformers, switchgear, bushings, motors, and generators. Advanced noise immunity (3 mA rejection at 10 kV) ensures stable readings in electrically noisy substations, while USB connectivity enables time/date-stamped data capture into PowerDB Lite for streamlined documentation and trending.
