DescriptionMegger MIT420/2 Insulation & Continuity Tester 50/100/250/500/1000V 600V CAT IV PI & DAR, Variable Voltage, Storage/RecallProduct Description:The Megger MIT420/2 Insulation and Continuity Tester (part number 1004-739) is a high-performance testing instrument designed for a wide range of applications, including avionic system tests, military (land, marine, and air communications), production line testing, electrostatic measurements, and electronic component testing. It features insulation resistance output voltages of 50V, 100V, 250V, 500V, and 1000V, with measurements up to 200GΩ. The MIT420/2 also allows for a variable test voltage range from 10V to 1000V, with an accuracy of -0% 2%, making it a versatile and precise tool.This model supports diagnostic testing with Polarization Index (PI) and Dielectric Absorption Ratio (DAR) tests. The tester can also function as a low resistance ohm-meter to measure resistance from 0.01Ω to 999kΩ, featuring an auto-null function that zeros out resistance up to 10Ω prior to testing. In addition, the MIT420/2 can measure capacitance from 0.1nF to 10μF and features bi-directional test current for polarity reversal without needing to switch test leads.The Megger MIT420/2 is equipped with live circuit detection to prevent measurements on live circuits, ensuring user safety and protecting the instrument. The device features an internal memory capable of storing up to 1000 test records for later recall, making it an ideal tool for diagnosing, repairing, and checking faulty electrical systems. The sealed IP54-rated case protects against water ingress, and the rubber over-moulding provides shock resistance and a secure grip. With a redesigned carry case and a three-year warranty, the MIT420/2 offers enhanced durability and performance for industrial and commercial applications.Key Features:Insulation resistance test voltages of 50V, 100V, 250V, 500V, and 1000V with measurements up to 200GΩVariable output voltage between 10V and 1000V for precise testingPolarization Index (PI) and Dielectric Absorption Ratio (DAR) diagnostic capabilitiesLow resistance ohm-meter with a measurement range of 0.01Ω to 999kΩ and auto-null functionBi-directional test current for polarity reversal without switching test leadsLive circuit detection to prevent testing on live circuits, ensuring safetyCapacitance measurement range from 0.1nF to 10μFInternal memory for storing up to 1000 test records for later recallSealed to IP54 for weatherproofing, including battery and fuse compartment protectionShock-resistant rubber over-moulding with excellent grip and durabilityComes with a redesigned carry case, back stand, and 6-cell battery compartmentWhat’s Included:Red Lead 1.25m with probeBlack Lead 1.25m with probeRed Crocodile ClipBlack Crocodile ClipSP5 switch probe for remote testingInstrument rubber bootCalibration certificateOwner’s information CDHard carry case6 x AA batteriesThree-year warrantyProduct Video:
