Pen Prawf, ABS, Clip Nickel Haearn Platiog

Test pen is also called test pen, referred to as "pencil". It's an electrician's tool used to test whether there's live in a wire. There is a neon bubble in the pen. If the neon bubble emits light during the test, it indicates that the wire has electricity or is the live wire of the path. The nib and tail of the test pen are made of metal materials, and the pen holder is made of insulating materials. When using the test pen, be sure to touch the metal part at the end of the test pen. Otherwise, the neon bubbles in the test pen will not emit light because there is no circuit between the charged body, the test pen, the human body and the earth, resulting in misjudgment that the charged body is not charged.
