Megger MIT1015 Essential 10kV HV Insulation Resistance Tester

Megger MIT1015 Essential 10kV Insulation Resistance Tester

The Megger MIT1015 Essential 10kV Insulation Resistance Tester is a rugged, entry-level instrument designed for high-voltage diagnostic testing and maintenance of electrical assets. As part of Megger’s Essential range, it delivers professional-grade insulation resistance testing at a reasonable price point, without compromising on advanced analytical capabilities. Built to be reliable and precise, the MIT1015 is perfect for testing rotating machinery, transformers, switchgear, motors, generators, bushings, and high-voltage cables across industrial, utility, and maintenance environments.

The MIT1015 has a maximum test voltage of 10kV and can measure insulation resistance up to 20TΩ with high accuracy (±5% up to 2TΩ and ±20% up to 20TΩ). It features a short-circuit current of 3mA and allows users to select voltage steps from 40V to 1kV in 10V increments. The MIT1015 also includes capacitance measurement capabilities ranging from 10nF to 25µF, and current measurement from 0.01nA to 6mA, making it suitable for a wide range of insulation diagnostics.

The MIT1015 is powered by a long-lasting 10.8V, 5.2Ah lithium-ion rechargeable battery, that provides up to 4.5 hours of continuous testing at 10kV. A 30-minute quick charge provides approximately one hour of operation, and the unit can also be powered directly from AC mains power when needed. The MIT1015 includes a high-contrast, backlit LCD display that makes it readable in direct bright sunlight or low-light conditions. It also features analogue arc representation for visual feedback of insulation resistance values, as well as intuitive dual rotary controls and a graphical quick-start guide under the lid for convenience.

A built-in USB interface allows for the rapid transfer of test results to a PC, simplifying data management. The MIT1015 supports Megger’s PowerDB Lite software, which allows users to store, organise, and report up to 1000 test records efficiently. This makes it an excellent tool not only for field diagnostics but also for long-term asset condition monitoring and compliance documentation.
