"The MIT300, MIT310 and MIT320 testers all feature an analogue \/ digital display. Large characters (height 20 mm) provide a clear readout, and a graduated dial simulates the operation of an analogue instrument, thus giving a true analogue response. The MIT310A has a moving display for those who prefer a real moving needle. Black text on a white background ensures good legibility, even in poorly-lit conditions. The MIT300 series covers all situations encountered by fitters working on domestic, commercial and industrial electrical installations. These devices can be used in building maintenance, testing, inspection and servicing. Tough rubber armoured case, integrated protective cover and a live voltage warning. Protection index IP54.
