Megger MIT420/2 CAT IV Insulation Tester
The MIT420/2 Megger is an industrial insulation tester with multimeter tendencies. With variable voltage test ranges and up to 200GΩ, it is good for a variety of test scenarios and can accurately measure voltage and resistance as well as perform fast continuity tests. Primarily used to detect motor winding and cable faults by maintenance workers and installers, with results on a dual display.
Megger MIT420/2 Features:
- CAT IV 600 V rating – provides greater safety when testing at higher voltage levels
- Adjustable insulation test voltages – provides 250 V to 1000 V or 50 V to 1000 V.
- Dual digital display readout – allows display of complimentary test information simultaneously (for example: MΩ plus test voltage or MΩ plus leakage current)
- Digital and analogue arc display – includes not only the digital readout but also Megger’s patented analog arc to replicate the response of a moving coil display
- Exceptional measurement range from 20 GΩ to 200 GΩ – highest insulation test range available on the market, providing a superior range of measurement applications.
- Choice of 20 mA or 200 mA continuity testing – allows user to select lower continuity range thus increasing battery life considerably
- Continuity auto-test capability – enables real twohanded operation without the need to press the test button
- Adjustable continuity limit alarm – allows pass/fail limits to be sent to speed testing
- Automatically perform PI and DAR tests – user is able to quickly perform two important diagnostic tests. . . Polarization Index (PI) and Dielectric Absorption Ratio (DAR)
- True RMS voltage measurement – allows accurate voltage measurement on noisy lines
- Auto ranging voltage measurement – automatically adjusts range from millivolts to 600 V AC or DC,
- eliminating the need to keep changing ranging
- Live circuit warning – automatically warns of contact to a live circuit, voltage is displayed and testing is inhibited
- Auto fuse warning – warns of fuse failure automatically.
- No need to test the fuse manually.
- Buzzer select button – enable or disable buzzer as required with resistance also displayed on the screen
- Insulation testing up to 1000 V and 200 GΩ range
- Stabilised insulation test voltage (New)
- Single range, faster continuity testing from 0.01 Ω to 1 MΩ (New)
- PASS/FAIL indication (New)
- Test voltage display (New)
- IP54
