Product Description

Professional Intelligent Tester Pen with Magnetic Tip Electrical Voltage Detector Pen for Electrician Maintenance Work

Product Description

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.
A contact voltage tester (also commonly known as a test pen or neon lamp voltage tester) is a basic electrical safety tool used for preliminary detection of the presence of AC voltage in circuits, sockets, or conductors. Its core component is a built-in neon lamp; when the tip of the test pen contacts a live source, and the user touches the contacts on the back to connect the circuit, the neon lamp illuminates.
The tool's housing is primarily made of ABS plastic (acrylonitrile-butadiene-styrene copolymer). This material was chosen because of its excellent balance of properties, meeting key requirements for electrical safety and tool durability.

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.
