Megger MIT210 MIT Series Insulation Resistance Testers

Megger MIT210 is a 1000 V insulation and continuity tester designed for electrical contracting, site maintenance, and service departments. Renowned for its compact and robust design, it is one of the smallest insulation testers available, making it ideal for engineers who need to carry equipment for extended periods. It features Megger’s patented DART (Digital Arc) display technology, combining a precise digital readout with an analog pointer to observe circuit charge and discharge characteristics.

Key Features

Insulation Testing: Performs testing up to 1000 MΩ at 1000 V. It supports test voltages of 250 V, 500 V, and 1000 V, covering a wide range of low-voltage applications.

Continuity Testing: Tests continuity at 200 mA down to 0.01 Ω resolution, ensuring compliance with international safety standards (BS7671, HD384).

Safety Features: Includes Live Circuit Warning (>25 V) and Test Inhibit (>50 V) to prevent accidental testing on live circuits, enhancing operator safety. It also features an automatic discharge function for capacitive circuits.

Display & Interface: High-contrast LCD with a logarithmic analog arc for easy trend viewing. Includes a continuity buzzer with a <2 Ω threshold for quick cable testing.
