The MIT300 series of insulation and continuity testers have been developed to meet the needs of today’s electrical contractors. They are not only durable and easy to use, but also incorporate a comprehensive set of features designed to ensure operator safety, even under conditions of accidental misuse.
The MIT310, MIT320, and MIT330 testers use both digital and analogue displays that simultaneously show the test results numerically, and in the form of a moving-arc bar graph that accurately simulates the operation of an analogue meter.
All products in the MIT300 range offer automatic discharge of the circuit after testing, audible and visual warning if the test probes are applied to a live circuit, and a test inhibit feature which operates automatically under live circuit conditions. The units also conform fully to IEC 61010-1 for use in Category III 600 V applications, and provide all of the facilities needed to meet insulation testing requirements relating to the current edition of the IEE Wiring Regulations.
All instruments in the the MIT300 range provide indication of insulation resistance up to 999 MΩ, 200 mA continuity testing, a fast-reacting continuity buzzer, and facilities for nulling the resistance of the test leads. The entry-level MIT300 offers insulation test voltages of 250 V and 500 V, while the remaining models allow testing at 250 V, 500 V, and 1000 V.
