The Megger MIT320 and MIT330 insulation testers feature the popular Megger digital/analog display. Large 20mm high characters provide very clear readout, combined with an analog arc for the feel of an analog instrument with a true analog response.

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 is finished.

No buried functions mean it is obvious how to use the Megger MIT310/MIT310A. Color coded ranges help test selection, reducing testing time, and help with fault location. A user guide in the lid provides all the basic information. 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. Both the display and the range selected can be read in the dark because the MIT320 and MIT330 have backlit displays and range selections.

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.

Megger MIT320 / MIT330 Safety features Include:
  • Safety Interlock – prevents unsafe connection of test leads.
  • Safe contact detectors – Even if the MIT is connected to a live circuit while on continuity setting the tester will remain safe and not be damaged.
  • Live voltage warning – alerts the operator when a circuit voltage over 25 V exists.
  • 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.

All the MIT instruments meet or exceed the UK and International Wiring Regulations, including requirements of BS7671 and VDE 0413 parts 1 and 4, HD 384, IEC 364, NFC15-100, NEN3140, ES59009 and EN 61557. In addition the range meets the requirements of IEC 61010-1 for safe connection to a 440 V Installation Category III supply (600 V Phase to Earth).

The MIT330 additionally offers the facility to save test results to internal memory. Over 1000 results can be saved on site, and downloaded to a computer when convenient. Data is stored in non-volatile memory, being retained when the instrument is switched off or batteries are exhausted.

A Job reference number can be selected for a range of results, allowing separate locations to be tested with the same tester and easily separated when downloaded. A memory bar graph acts as a ‘Fuel Gauge' showing how much memory has been used. Test results are downloaded to CSV (Coma Separated Variable) spreadsheets, and can be imported into Microsoft Excel. If certificates or reports are required, the results can be downloaded directly into Megger Powersuite Professional with a range of features for creating professionally finished documentation.

The MIT300 series has applications in all aspects of domestic, commercial and industrial electrical contracting, building maintenance, testing, inspection and servicing. Combining both insulation testing and continuity testing, each instrument caters for all aspects of fixed wiring installations. Further applications can be found in panel building, testing of motors, generators, switchgear and power tools, street lighting and low volume manufacturing environments.

The MIT320 and MIT330 are supplied with a full 3 year warranty.
