3PCS Electrical Tester Pen with LED Light

Responsive Electrical Tester Pen

Bright LED Light
This tester pen features a bright LED light that can be used during daytime, making it a perfect addition to any electrical kit. It easily distinguishes between live and neutral lines, providing clear visibility for safer handling.

High-Quality & Safe
Constructed with a high-quality, anti-drop insulation PS handle and durable accessories like a screw rod, slotted point screwdriver, nut, spring, neon bulb tube, and resistance block, our tester pen ensures safety and reliability. With 4 functions, it prepares you for any electrical task.

Self Check Function
Before use, perform a self-check by holding the pen tip with one hand and touching the tail with the other. A lit light indicates normal operation and sufficient power, while no light suggests a need to replace the battery.

Automatically Inductive Detection
Simply hold the pen close to the insulation of wires, the plastic shell of appliances, or other insulating materials. If the light turns on, the line is live. The brightness indicates the voltage level of the circuit—brighter indicates higher voltage, dimmer indicates lower voltage.

Find Line Breakpoints
Locate breakpoints by touching the bottom of the pen with one hand and the wire with the other. The light will go out at the breakpoint. This is particularly useful for diagnosing issues in daily appliances like rice cookers, computers, and plug-in boards.

DC Detection
For DC detection, touch the bottom of the pen with one hand, the positive terminal of the battery with the tip of the pen, and the negative terminal with the other hand. A lit light confirms the battery is fully charged, and the absence of light indicates it needs charging.

This pen is trusted by electricians for its reliability and ease of use, making it an essential tool for professionals and DIY enthusiasts alike.
