Megger MIT300 Series

Megger MIT300 Series

Megger Insulation and Continuity Testers Designed for Durability

  • Extremely easy to use
  • Tough rubber armoured case
  • Self contained protective cover
  • Live circuit warning
  • Weatherproof to IP54
  • Intelligent Safety System for protection.

The Megger insulation testers will take the bashing that testers receive when they are on site

They are rubber armoured and have an integral solid lid to cover the display. The lid has a heavy-duty hinge that locks away underneath when in use, making it easy to use and impossible to lose. And you don’t need to pull out the test leads to shut the lid.

The Megger MIT insulation testers are easy to use and quick to learn

There are no buried functions, so it is easy to use these new insulation testers. The colour coding helps test selection, speeding up testing time and helping you identify faults fast. The quick start guide in the lid keeps all the basic information at hand if you need it

Your safety is Meggers number one concern. These safety features look after you and the tester

  • Safety interlock to prevent unsafe connection of the test leads
  • Safe contact detector keeping you and your tester safe during continuity testing if it’s accidentally connected to a live circuit
  • Live voltage warning alerts the user to a circuit voltage over 25 V when insulation testing
  • Safety lockouts
    • Prevents continuity testing on live circuits
    • Prevents insulation testing when circuit voltage is greater than 50 V

Hands free operation

MIT300 series insulation testers are well balanced to hang comfortably around your neck enabling hands free operation when you need it. The continuity test and buzzer start automatically when you connect to a circuit, saving you time. Insulation tests can be started using a switched probe or the test button on the front of the tester.
