Discontinued!
This product has been discontinued and is no longer available.
This is the direct replacement:
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.
Applications
Designed to cope with the additional requirements of the telecommunications industry, MIT Models 480, 481 and 485 include 50 V and 100 V range insulation testing as standard, plus higher voltages as required.What's Included
Instrument Safety
The MIT400 Series instruments are designed to meet all of the requirements of IEC1010-2 and EN61557 and meets the safety requirements for use on CAT IV 600 V.
Also, fast detection circuitry prevents damage to the instruments if accidentally connected to live circuits or across phases.
