Non-Contact Voltage Tester Pen | Live Wire & Breakpoint Detection 12–1000V

This handheld electrical test pen is designed for quick and reliable voltage detection without direct contact with live conductors. Using non-contact voltage (NCV) technology, it allows users to safely identify live wires, neutral wires, and circuit breakpoints during installation, maintenance, and troubleshooting tasks.

The tester features a large LCD display for clear voltage indication, combined with audible and visual alerts to warn of live electrical fields. High and low sensitivity modes enable accurate detection across a wide voltage range, making it suitable for both household and professional electrical environments.

Additional functions such as ambient temperature measurement, built-in flashlight, and automatic power-off enhance usability in real-world conditions. Its slim pen-style design with a pocket clip makes it easy to carry and use on the job.

Typical applications include:

• Live wire and neutral wire identification

• Non-contact AC voltage detection

• Circuit breakpoint location

• Electrical installation and maintenance

• Home, workshop, and trade electrical checks
