Non-Contact Voltage Tester Pen Electrical Detector

Reliable Non-Contact Voltage Detection for Everyday Electrical Work

This non-contact voltage tester pen is designed for quick, safe, and convenient checking of live circuits at home, in the workshop, or on-site. With audible and visual alarms, it allows you to confirm the presence of voltage without touching bare wires, helping reduce the risk of accidental electric shock during troubleshooting and repair.

The tester automatically distinguishes live (fire) and neutral (zero) lines, giving you a clear indication of which conductor is energized. A bright LED at the tip illuminates the test area, improving visibility in panels, outlets, and tight spaces. The compact, pen-style body (156 x 20 x 20 mm, approx. 45 g) is easy to carry in a pocket or tool pouch and comfortable to hold during extended use. Powered by 2 x 1.5V AAA batteries (not included), it features auto power-off to help conserve battery life. Suitable for typical indoor environments with an operating temperature range of 0-40°C.

Why It's a Smart Choice

• Non-contact operation - Detects voltage without touching bare conductors, reducing direct exposure to live parts.
• Clear sound and light alarms - LED indication and audible beeps provide immediate feedback when voltage is present.
• Portable and easy to use - Pen-style design, simple button operation, and tip light make it practical for both professionals and homeowners.

FAQ

Q: Can this tester detect voltage through insulated wires?
A: Yes. It can detect voltage on most plastic-insulated wires by sensing the electric field near the conductor.

Q: Can I use it through metal conduit or metal sheathing?
A: No. It cannot detect voltage through metal conduit or metal-clad sheathing, as the metal blocks the electric field.

Q: Are batteries included?
A: No. The tester requires 2 x 1.5V AAA batteries, which are not included.

Q: How do I know the tester is working before use?
A: Turn it on and test it on a known live outlet or cable. Confirm that the light and sound alarms activate before relying on it for safety checks.
