Non-contact voltage tester

LASERLINER ActiveFinder Non-Contact Voltage Tester, 158 mm, CAT III 1000 V

Find live wiring without touching a conductor, with a built-in torch for dark installation spaces.

The LASERLINER ActiveFinder non-contact voltage tester detects AC voltage from 24 V AC up to 1000 V AC in cables, sockets, lamp holders and fuses. It comes in a pen-sized 158 mm housing weighing just 48 g, with a bright LED and audible indication.

Detection without contact with the conductor

The tester registers the electrostatic fields produced by alternating voltage in the 50 … 60 Hz range. You check sockets, lamp holders and fuses without exposing or touching live parts.

ZOOM function for tracing cables inside walls

Boosted sensitivity traces live lines at depths of roughly 4 cm below the plaster. Handy for locating a cable run before drilling and for pinpointing a break in a cable or wire.

Single-pole identification of L and N

The tester distinguishes the phase conductor from the neutral straight at the socket or terminal. The bright LED indication stays readable inside shafts and distribution boards.

Built-in torch with separate button

The torch switches on independently of measuring and stays available while you work in a dark room or behind a cabinet. The impact-resistant housing takes daily site use, with an operating range from -10 °C to 50 °C.
