Voici le produit de remplacement direct :
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.
Caractéristiques
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.
In addition, the voltage detection test inhibit feature has been raised to 75 V (from 50 V), to allow testing of cables with coactivity coupled induced voltages, which would normally inhibit such testing with a 50 V protected instrument.
