Screwdriver with Circuit Tester pen
Electric Tester Pen (also called a test pen or voltage tester pen) is a portable, hand-held electrical tool widely used by electricians, maintenance workers and in industrial/hardware scenarios to detect the presence of AC voltage in electrical circuits, wires, sockets and electrical equipment. It is a basic and essential safety tool for electrical operation and fault troubleshooting.

Common Types
Neon Tester Pen
The basic and most economical type, with a neon bulb inside. It judges the presence of voltage by the brightness of the neon bulb (no numerical display), suitable for detecting AC voltage of 50~500V (the mainstream voltage range for household and industrial low-voltage circuits).
Digital Tester Pen
Equipped with an LCD screen, it can directly display the measured voltage value (e.g., 220V, 36V). It supports low-voltage detection and has higher accuracy, suitable for fine circuit testing.
Non-contact Electric Tester Pen
An inductive type that does not need to touch the metal conductor. It triggers a light/sound alarm when close to a live object (usually detecting AC 90~1000V), which is fast and safe for quick fault location of wires and sockets.
Usage:
To use it, one simply places the tip on the conductor to be tested and touches the end cap with a finger. If the neon bulb lights up, voltage is present.
It is a fundamental, inexpensive, and essential tool for any basic electrical work, providing a quick and reliable first check for electrical safety.
Typical Application Scenarios
Daily inspection of household and industrial sockets, switches and wires;
Pre-operation safety confirmation of electrical equipment maintenance (confirm no electricity before construction);
Quick troubleshooting of open circuits, live wire misconnection and other faults in low-voltage electrical circuits;
Electrical safety detection in construction, fire protection and hardware installation projects.
