Megger MIT220 Insulation and Continuity Tester

The Megger MIT220 Insulation and Continuity Tester will find applications in electrical contracting, both on domestic and industrial systems as well as site maintenance and service departments. The MIT220 insulation and continuity tester is ideal for testing transformers, motors, generators, switchgear, panel building, domestic appliances, power tools as well as fixed electrical wiring systems. The compact nature of the MIT 220 makes it ideal for engineers that need to carry them for extended periods. The MIT220 offers a range of safety and operation features. The display provides a combination of digital readout and analogue display using Megger’s patented DART display technology. The Megger MIT220 has the benefits of an LCD screen with clear and accurate measurement display and an analogue pointer response for evaluating circuit charge and discharge characteristics. This digital/analogue insulation and continuity tester's housing is in tough ABS, designed to withstand the rigours of hard use and is small enough to drop into your pocket when not in use.

Automatic continuity testing is performed at 200 mA to ensure compliance with international requirements. The Megger MIT 220 insulation and continuity tester will measure up to 100Ω on continuity, of which 0-10Ω is performed at greater than 200mA to meet international electrical testing requirements. Lead null is possible up to 9.99Ω of test lead resistance, ensuring the ability to null fused test leads as well as standard leads. The continuity buzzer operates at a 2 ohm threshold and provides a means of rapid cable testing and circuit identification, with voltage protection should you accidentally touch a live circuit. Insulation testing is possible up to 1000MΩ on both 250V and 500V ranges. Auto discharge ensures all circuits are safely discharged after testing.
