Model: MIT410/2
Part Number: 1004-735
The MIT400/2 Series insulation and continuity testers are designed for electrical and industrial testing. In addition, they have an exceptionally wide range of applications in electrical installations, cable testing, motor testing, automotive, ESD, panel building, avionics, maintenance etc.
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 10 V to 1000 V in 1 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 compartments with separate fuse access.
All instruments are over-moulded for increased protection and achieve an IP54 weatherproof rating.
