A line tester is an electrical tool used to test the presence of current and to identify phase / live wire in electrical installations. When the metal tip of the tester comes in contact with a live circuit, a small light encased inside the handle of the tool starts glowing.
It is easier to use and cheaper than other measuring devices like multi-meters. Apart from that, it can also be used as a screwdriver to tighten the masonry screws. As you can guess, line testers are practically life-saving devices and should always be used before touching any piece of wiring or metal part in a circuit.
No electrician can go about his day without a reliable line tester in his toolkit. Pressfit has been the go-to line tester brand for lakhs of electricians in India and abroad for more than 2 decades! Under the child brand of Press Teak, we offer a range of robust and reliable line testers that are indispensable for electricians, households, and offices.
The main purpose of the line tester is to detect the presence of electricity in the circuit line. If the metal tip of the line tester comes in contact with a live cable, the neon lamp gets illuminated at the end of the tester. It acts as a quick signal to the user about the presence of electricity.
