Megger MIT525/2 | 5 kV Insulation Tester

The Megger MIT525/2 is a 5 kV insulation resistance tester engineered for professionals who require accuracy, safety, and efficiency. As part of the Advanced range, this instrument delivers reliable diagnostic testing for a wide array of electrical assets, from cables and transformers to motors and generators. Its robust, dual-case design provides exceptional durability and user protection, with an IP65 rating when closed to guard against dust and moisture ingress.

Designed for demanding industrial and power distribution environments, the MIT525/2 offers superior performance with up to 6 mA noise rejection, ensuring stable and precise measurements even in electrically noisy locations.

The instrument features a comprehensive suite of diagnostic tests, including Polarisation Index (PI), Dielectric Absorption Ratio (DAR), Dielectric Discharge (DD), and Ramp testing. The patented PI Predictor function can save valuable time on site by estimating PI results in as little as three minutes, optimising your testing workflow.

Safety is paramount, and the MIT525/2 is rated to CAT IV 600 V up to 3000 m, providing confidence during high-voltage applications. Its intelligent safety system includes multiple levels of voltage warnings to protect both the user and the instrument. With user-defined test voltages from 40 V to 5 kV, you have complete control over your testing parameters.

Data management is streamlined with on-board memory that stores time and date-stamped results. You can easily transfer data to a PC or mobile device via the isolated USB or wireless Bluetooth LE interface. This enables seamless integration with CertSuite Asset and PowerDB software for advanced analysis and reporting.

The rapid-charge Li-ion battery ensures the tester is ready when you are, offering up to 6 hours of continuous testing and operating from an AC supply for uninterrupted use. For technicians and engineers who need a dependable and feature-rich insulation tester, the MIT525/2 is the definitive choice.
