The Megger MIT400, MIT410, MIT420, MIT430, MIT480, MIT481, MIT485 series instruments have been developed specifically for the tele-communications industry. The insulation and continuity testers combine the latest range of measurement techniques with new instrument design to provide a state-of-the-art tester that is compact and comfortable to hold. The MIT480 series directly replaces the well-established BM80 product group, given greater functionality with simplified operation and greater application range.

The MIT481 is capable of saving test results for recall to the screen. A simple storage structure allows for a test number and screen results to be recalled individually.
