Reactive electrical tester pen, 70-250V waterproof voltage tester induced electrical pen, reactive electrical tester pen, non-contact voltage tester pen (1 piece)

Safe and High Quality: Our tester pen consists of a high-quality and durable PVC handle, a screw shaft, a slotted screwdriver, a nut, a spring, a neon tube, and a resistor block, ensuring safe use.

Automatic Induction: As long as it is close to the wire insulation, the plastic casing of the electrical device, etc., when the light comes on, it means the line is live. The brighter the light, the higher the voltage of the circuit being tested, and vice versa.

Finding Line Break Points: One hand touches the bottom of the pen and the pen tip touches the wire. The break point is where the light goes out.

It is used to find break points in everyday household appliances such as rice cookers, computers, and plug-in cards, etc.

Self-check function: When self-checking before use, please hold the tip of the pen with one hand and touch the tail with the other. When the light is on, it means the tester pen is working properly and has sufficient power. No indicator light means the battery needs replacing.

Bright light and waterproof: The pen is designed with a bright LED light, which is also a clear indicator when used during the day. Furthermore, it is waterproof, making it suitable for outdoor use.
