SMART CHIP: The test screwdriver is equipped with a wear- and scratch-resistant ABS casing. With a smart motherboard chip, this test pen features an enhanced chip control program, resulting in higher safety and a longer lifespan. ON/OFF POWER DETECTION: This voltage tester pen can test the power supply. If the plug core is in good condition, the green LED indicator will light up. If it does not light up, the plug core is disconnected and the contact is faulty. EASY TO CARRY: The 70-250V voltage tester is small and lightweight, saving space. You can easily take this pen with you to assist in your work, making it convenient to use. DETERMINE NEUTRAL AND LIVE WIRE: Our electrical tester can distinguish between the neutral and live wires. Insert the electrical needle into the socket; if the red and green lights illuminate together, the wire is live.
