Induction Test Pen AC Voltage Detector 24-250V

Reliable non-contact AC voltage testing in a compact pen-style tool

designed for everyday electrical checks, fault tracing and quick verification of live circuits. This induction test pen combines NCV (Non-Contact Voltage) detection with a practical screwdriver tip, giving electricians and DIY users a dependable way to work on outlets, switches, cables and appliances.

Operating in the 24-250 V AC range, the pen detects live voltage without touching bare conductors. As you move closer to a live wire, outlet or terminal, it provides a clear sound and light alarm so you can confirm power status before you begin work. The highlight color light offers instant visual feedback and improves visibility in dim panels, behind equipment or in tight spaces. The integrated negative pole probe socket allows simple connection to the COM input for additional measurements, supporting automatic detection for streamlined testing. Built with an ABS body and a chrome vanadium steel screwdriver bit, the pen is lightweight yet sturdy enough for regular use in domestic, workshop or onsite environments. The analog-only display style keeps operation straightforward, while the compact 160 × 28 × 27 mm form factor fits easily into a pocket, tool pouch or meter bag. Powered by two standard 1.5 V AAA batteries (not included), it is always ready for quick checks, from identifying live/neutral conductors to tracing line breakpoints and verifying switch operation.

Why It's a Smart Choice

• Non-contact AC detection from 24-250 V helps reduce direct exposure to live conductors during basic checks.
• Sound and light alarms, plus a highlight indicator, provide clear feedback in noisy or low-light work areas.
• Combined voltage tester and screwdriver function saves space in your toolkit and supports everyday electrical tasks.

FAQ

Q: What voltage range can this pen detect?
A: It is designed for AC voltage detection in the 24-250 V range, suitable for common household and light commercial circuits.

Q: Does it require direct contact with bare wires?
A: No. The NCV function detects voltage through insulation on cables, outlets and terminals, allowing contactless checks in most situations.

Q: Are batteries included with the tool?
A: No. The pen uses two 1.5 V AAA batteries, which need to be purchased separately.

Q: Can it help find a wire breakpoint?
A: Yes. By following the cable and noting where the alarm stops, you can locate probable breakpoints along a line.

Q: Is this suitable for beginners or only electricians?
A: The straightforward sound/light indicators make it accessible for DIY users, while its feature set also supports routine tasks for trained electricians.
