Megger MIT410/2 SERIES CAT IV Insulation Testers For Electrical And Industrial Maintenance Engineers

Insulation testing has been enhanced with feedback controlled test voltages to limit over-voltage to 2%, rather than the industry standard 10-20%. A variable range has been added to allow any intermediate voltage from 50 V to 1000 V in 10 V steps, where application specific test voltages are required that do not appear in the standard ranges. Continuity testing is now significantly faster, and a single auto-ranging 0.01 Ω to 1.0 MΩ function replaces the “ohms” and “kOhms” ranges. Retained are the 200 mA and 20 mA test options. Replacing the original MIT400 instruments the new units feature a redesigned case, back-stand, and 6 cell battery compartment with separate fuse access. All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating. The range consists of four instruments: MIT400/2 250 V, 500 V and 1000 V MIT410/2 50 V, 100 V, 250 V, 500 V and 1000 V Polarisation Index, Dielectric Absorption Ratio MIT420/2 50 V, 100 V, 250 V, 500 V and 1000 V Polarisation Index, Dielectric Absorption Ratio, Variable Test Voltage and result storage MIT430/2 50 V, 100 V, 250 V, 500 V and 1000 V Polarisation Index, Dielectric Absorption Ratio, Variable Test Voltage and Bluetooth download
