Electrical Tester Pen with LED Light - 3PCS

The Responsive Electrical Tester Pen is a must-have tool for electricians and DIY enthusiasts alike. With a voltage range of 70-250V, this pen can easily distinguish between live and neutral lines, making it easy to detect breakpoints in electrical circuits. The pen features a bright LED light that can be used during the day, ensuring visibility in any lighting condition.

Constructed with high-quality and anti-drop insulation materials, including a PS handle, screw rod, slotted point screwdriver, nut, spring, neon bulb tube, and resistance block, this tester pen is durable and safe to use. It also has a self-check function - simply hold the pen tip with one hand and touch the tail with the other hand to ensure it has enough power.

The pen features an automatic induction function that detects live wires when in close proximity to insulation or plastic shells of electrical appliances. The brightness of the LED light indicates the voltage of the tested circuit, making it easy to identify potentially hazardous areas.

Additionally, the tester pen can be used to find breakpoints in household appliances such as rice cookers, computers, and plug-in boards. By touching the bottom of the pen with one hand and the wire with the other, the light will go out at the breakpoint.

Furthermore, the pen can also be used for DC detection by touching the positive and negative terminals of a battery. A lit LED light indicates a fully charged battery, while no light indicates the need for a replacement.

Overall, the Responsive Electrical Tester Pen is a versatile and essential tool for anyone working with electrical circuits. Its multifunctional features and high-quality construction make it a reliable choice for professionals and amateurs alike.
