Main Features:
When the pen head senses or detects the voltage, the white part of the pen head will emit light and beep. It is easy to detect the live line and know which line has dangerous voltage.
There is a button in the middle of the inductive pen. Press it and a bright LED will light up at the pen head. It can be used as a flashlight. In a dark work place, you can easily complete the line work without the help of flashlight!
Power supply: 2 x AAA batteries (not included)
