Intelligent Non-Contact AC Voltage Tester Pen

Intelligent Non-Contact Voltage Testing for Everyday Electrical Work

This intelligent voltage tester pen combines non-contact AC voltage detection with a practical screwdriver function, making it a versatile tool for electricians, technicians, and home users. Designed to test live circuits quickly and safely, it detects the presence of AC voltage in outlets, switches, circuit breakers, cables, and power strips without direct metal-to-metal contact. A built-in LED indicator clearly shows voltage status, helping you identify live and neutral lines, trace faults along a cable, and verify continuity in basic household wiring tasks.

The tester operates within a measuring range of 70-250V AC, suitable for most household and light commercial applications. The tip is made from chrome vanadium steel for strength and durability, while the ABS shell provides full insulation and impact resistance. Its compact size of about 140 x 20 mm (approx. 5.51 x 0.79 in) fits easily in a pocket, tool belt, or shirt pocket, and the integrated clip keeps it secure during work or travel. Powered by three LR41 batteries (included), the high-brightness LED remains visible even in well-lit environments, supporting reliable use indoors, in workshops, or on job sites.

The pen supports several core functions: live/neutral line detection with red and green LED indications; line tracking, where the LED shows whether a wire is continuous or broken; and basic switch and plug checks to confirm whether the internal conductors are intact. These features make it suitable for use in electronic assembly, appliance service, automotive electrical checks, and general household maintenance where quick, visual confirmation of power status is required.

Why It's a Smart Choice

• Non-contact AC detection improves safety by minimizing direct exposure to live conductors.
• Combined tester and screwdriver design reduces the number of tools you need to carry.
• Clear LED indications and compact, insulated housing support fast, reliable work in a wide range of environments.

FAQ

Q: What voltage range can this tester detect?
A: The tester is designed for AC voltage detection in the range of 70-250V, which covers most common household and light commercial circuits.

Q: Can it distinguish between live and neutral wires?
A: Yes. The LED indicator uses different colors to show live and neutral line status, helping you quickly identify the active conductor in a circuit.

Q: Is it suitable for continuous professional use?
A: The chrome vanadium steel bit, ABS insulated shell, and high-brightness LED are designed for frequent use in workshops, service centers, and on-site maintenance, provided it is used within its specified range and according to standard electrical safety practices.

Q: Do the batteries come included?
A: Yes. The tester is supplied with three LR41 button cell batteries so it is ready to use out of the box.
