Megger MIT420/2 Industrial Telecom Insulation Tester

With its on board storage, the MIT420/2 is the next step up from the MIT410/2, being able to store recordings on the device reduces down time as there is no writing down or keying in results on an external device. However, the MIT420/2 still sticks to the same design which makes their testers so simple to use, as well as being able to withstand any environment.

One of the main differences between the MIT410/2 MIT420/2 is that the MIT420 can measure capacitance from 1nF-10μF. This coupled with the previously mentioned on board storage make it perfect for an engineer that requires an instrument with more advanced capabilities. The selectable test voltages for insulation are 50V, 100V, 250V, 500V and 1000V with a range of 200GΩ, there is insulation test voltage variable from 10V to 1kV. Also featured is the ability to perform Polarisation index and Dielectric Absorption Ratio diagnostic tests. Continuity measures 0.01Ω to 10MΩ with an auto reverse polarity feature. The voltage measures to 600V AC/DC, can measure mV AC/DC and has a frequency measurement of 45-450Hz.
