Major Tech AC Voltage Detector MT401

The pocket sized MT401 voltage detector is ideal for general use. The tip of the pocket-sized tester will glow red when within close proximity of an outlet, terminal strip or power cord where voltage is present. The unit comes complete with batteries and can be used on voltages up to 600V AC. The MT401 has a double injection rubber house, and has a unique feature with a built-in LED torch for those dimly lit areas. The MT401 tests for energised circuits and defective ground, whether it’s for electricians, maintenance, service, safety personnel or the do-it-yourselfer around the house.
