The new MIT300 Series features a large display and hands-free operation. The tough, rubber armored case is designed for rough handling and weatherproof to IP54. A rigid cover folds up to protect the front panel when not in use. Intelligent safety features include:
  • Safety Interlock – prevents unsafe connection of test leads
  • Safe contact detectors – the tester will remain safe and not be damaged if connected to a live circuit while on continuity setting.
  • Live voltage warning – alerts when circuit voltage is >25V.
  • Safety lockout – inhibits test when circuit voltage is >50V.
  • Continuity check – prevents a continuity test on a live circuit.
Each model includes a 200mA continuity test function and continuity buzzer. All models except the MIT300 measure DCV & ACV (50/60Hz) to 600V. The MIT330 adds memory for storing 1000 test results and a USB interface. The MIT310A has an analog meter display for those who prefer a moving needle.
