MIT400 Series CAT IV

Insulation Resistance and Continuity Testers

DESCRIPTION

The Megger MIT400 Series insulation and continuity testers

has been designed for electrical testing by power utilities,

industrials, telecommunication companies, commercial/

domestic electricians and anyone with unique test voltage

requirements. The wide range of features also makes

the MIT400 Series ideal for maintenance technicians and

engineers.

They replace the well-established BM400 insulation tester

range, giving greater functionality with simplified operation,

greater application range and increased safety.

The range

The range consists of eight instruments:

MIT400 250 V, 500 V and 1000 V

MIT410 50 V, 100 V, 250 V, 500 V and 1000 V plus PI

and DAR

MIT420 Same as Model 410 plus result storage

MIT430 Same as Model 420 plus Bluetooth

download

MIT480 50 V, 100 V
