Product overview Extremely easy to use Durable rubber armored housing Autonomous protective case Voltage presence warning in electrical circuit Weatherproof protection according to IP54 standard Intelligent safety system for protection The MIT300 series of insulation and circuit integrity testers was developed to meet the needs of modern electricians. They are not only durable and easy to operate but also feature a comprehensive set of functions designed to ensure operator safety even in cases of accidental misuse.
The MIT310, MIT320, and MIT330 testers utilize both digital and analog displays, which simultaneously show test results numerically and as a histogram with a moving arc that accurately simulates the operation of an analog meter. However, if you prefer a true analog device, Megger offers the MIT310A, which has similar characteristics to the MIT310 but with a traditional moving coil meter instead of a digital display.
All products in the MIT300 line offer automatic circuit discharge after testing, audible and visual warnings if test leads are connected to a live circuit, and a test lock function that activates automatically under voltage conditions. The devices also fully comply with IEC 61010-1 standards for use in Category III 600 V equipment and provide all necessary features for insulation testing as per the current edition of the IEE Wiring Regulations.
All MIT300 series devices provide insulation resistance measurement up to 999 MΩ, integrity testing at 200 mA, a fast buzzer for circuit integrity verification, and a resistance zeroing function for test leads. The basic MIT300 offers insulation test voltages of 250 V and 500 V, while other models support testing at 250 V, 500 V, and 1000 V.
