Product Details

MIT 300 Series Insulation & Continuity Testers

A range of insulation testers that meet the relevant requirements of EN61557, BS7671, HD 384, IEC 364 and VDE 0413 for applications in all aspects of electrical contracting, building maintenance, testing, inspection and servicing.

20mm LCD display with true analogue response
Tough rubber armoured case with self contained display cover that locks away underneath the instrument during use
Designed to hang comfortably around the neck for hands-free, or for bench use
Automatic 200mA fast continuity test on connection to the circuit
Lead resistance nulling on continuity allows for use of fused test probes
Automatic discharge of circuit under test
Safety input terminal interlock - prevents unsafe connection of test leads
Intelligent Safety System - even if connected to a live circuit whilst on continuity setting the tester will remain safe and undamaged
Live voltage warning alerts the operator when a circuit voltage over 25V exists when insulation testing
Safety lockout prevents the test from operating when the circuit voltage is > 50V
Continuity check - prevents a continuity test or buzzer test on a live circuit
3 phase safe - will not be damaged if connected across phases
Locking test button
Meets the requirement of BS EN 61010-1 for safe connection to a 440V Installation Category III supply (600V Phase to Earth)


Moving coil display

MIT320 benefits from the following additional features:

Backlit display and range selection ideal for low light environment
