Set of 5 Voltage Tester Pens, Smart Non-Contact Induction Test Pens - Voltmeter Power Detector, Electric Screwdriver Indicator, AC Voltage Tester Pen - LIAIKI

Product Description: 1. Place your hand over the cap and touch the contact point, then insert the electric pen into the live wire. The electric pen will light up with red and green bicolor lights. This indicates that the wire is live; 2. The motherboard features a professionally upgraded chip control program, resulting in greater safety and a longer lifespan. 3. Touch the electric pen to the contact point. If the wire core is undamaged, the green LED will illuminate. If it does not illuminate, the wire core has a poor connection. 4. When the line is detected, the green LED is on, the line is normal, and the disconnection LED is off.

Product List: 5 Voltage tester pens. 【Distinguish Live/Zero Lines】 Simply place your hand over the cap and touch the pole. Insert the test pen into the live wire. The green indicator on the test pen is the zero line, and the pen will light up with a two-color indicator for the live wire. 【Detection Point Assessment】 The electroscope can quickly determine the live wire. If the line is normal, detect along the line. If the green light on the electroscope does not illuminate, it means the line is disconnected; otherwise, the line is normal. 【Electrical Switch Detection】 The test pen touches the contact pin. If the wire's inner core is undamaged, the green LED indicator will light up. If it doesn't light up, it means the wire has a poor connection. 【Humanized Design】 The test pen is small and portable. The clip design is convenient for electricians to carry during maintenance, and the light can be turned on for easy identification. 【Good Conductivity】 Our test pen is made of high-hardness chrome-vanadium steel, which has good conductivity. The motherboard features professionally upgraded chip control software, making it safer and longer-lasting.
