Non-Contact Voltage Tester Sensor Pen 90-1000V AC

Quick, Safe Voltage Detection in Your Pocket

This non-contact Voltage Tester Sensor Pen provides a fast, reliable way to check for live AC voltage in outlets, cables, and electrical components. Designed in a compact pen-style body, it fits easily in a pocket or tool bag and is ready whenever you need to verify power status on-site or at home.

The tester detects AC voltage in the 90-1000V range with a frequency range of 50-500 Hz, suitable for most residential and commercial applications. To use, simply bring the tip close to the conductor or terminal: if voltage is present, the pen's tip illuminates red to indicate a live circuit. No direct metal contact, test leads, or complex settings are required. The insulated, non-conductive housing supports safer operation, while the low power consumption design helps extend battery life.

Powered by 2 x AAA batteries (not included), this tester is ideal for checking wall sockets, circuit breakers, fuses, extension cords, junction boxes, lighting circuits, and more. Its straightforward operation makes it a practical addition to the toolkit of electricians, maintenance staff, installers, and informed DIY users.

Why It's a Smart Choice

• Non-contact testing - Detects live AC voltage without touching bare conductors, reducing the risk of accidental shocks.
• Clear visual indication - Red tip illumination provides an immediate, easy-to-read live/neutral status.
• Portable and convenient - Pen-style design and battery operation make it easy to carry and use in tight or hard-to-reach spaces.

FAQ

Q: What voltage range can this tester detect?
A: It detects AC voltage from 90V to 1000V within a 50-500 Hz frequency range.

Q: Does it require direct contact with bare wires?
A: No. It is a non-contact tester; you only need to bring the tip near the conductor or outlet opening.

Q: Are batteries included?
A: No. The tester is powered by 2 x AAA batteries, which are not included.

Q: Where can I use this tester?
A: It is suitable for checking outlets, switches, circuit breakers, power cords, junction boxes, lighting fixtures, and similar AC installations within the specified voltage range.

Q: Is it a replacement for a multimeter?
A: No. This tool is designed specifically for quick voltage presence checks. For detailed measurements (current, resistance, exact voltage), a multimeter is still required.
