Megger MIT310A Analogue Insulation and Continuity Tester

The Megger MIT310A is a fully analogue insulation and continuity tester designed to carry out insulation, continuity and voltage measurements.

This tester has a moving coil display for those who prefer a real moving needle. Black decals on a white background give high contrast, even in poor light conditions.


Megger MIT310A Key Features:

  • Tough:
    • Designed to take the bashing that testers receive on site, the Megger MIT insulation testers are rubber armoured
    • The rigid display cover folds right out of the way during testing and locks down to protect the display when it‘s finished
    • Weatherproof to IP54
  • Simple to use:
    • No buried functions mean it‘s obvious how to use the Megger MIT
    • Colour coded ranges help test selection, reducing testing time and help with fault location
    • A user guide in the lid provides all the basic information
  • Hands free use:
    • It hangs comfortably around the neck for hands-free use because the instrument is carefully balanced
    • Continuity and buzzer testing starts automatically on connection to the circuit
  • Safety features:
    • To protect the user and the tester from incorrect use the MIT series all have an extensive range of features known as the Megger Intelligent Safety System including:
      • Safety Interlock – Prevents unsafe connection of test leads
      • Safe contact detectors – Even if the MIT is connected to a live circuit whilst on continuity setting the tester will remain safe and not be damaged
      • Safety lockout – Prevents the test from operating when the circuit voltage is >50 V
      • Continuity check – Prevents a continuity test or buzzer test on a live circuit
