The MIT400 mk2 series insulation and continuity testers are designed not just for Electrical and Industrial, but with an exceptionally wide range of applications from electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance etc.

All primary results are displayed in the larger digital display and repeated on the analogue arc. Auxiliary test information such as frequency, leakage current, insulation or circuit voltage is displayed in the smaller secondary digital display.

The MIT420/2 adds additional features required for engineers working on more demanding applications. Functions such as PI and DAR, capacitance measurement and a greater range of test voltages increase the suitability for applications such as: manufacturing/production testing, panel building, railway and other transportation, motor testing, cable inspection/quality control, street lighting maintenance, avionics ground testing and maintenance, military applications.

The MIT420/2 also includes 25 and 50 V ranges for testing communication circuits for signalling controls:

Elevator service engineers.
Street lights (Pedestrian controls).
Machines and saftey interlock/commisioning service.
HVAC controls.
Robotic Power and Control.
