Electrical Mains Tester Screwdriver

Electrical mains phase / line test screwdriver, with neon light to indicate voltage / live circuit.

Magnifying window in handle ensures an excellent view of the illuminated display.

Following information supplied by manufacturer :

The voltage indicator is suitable for testing AC voltages from 100 up to 250V against earth.
The metal part on top of the indicator must be touched to operate it and the earthing position of the user largely determines whether it lights up or not.
Note : Failure to light up therefore does not indicate with certainty that no voltage is present.
