Intelligent Non-Contact Voltage Tester Pen 12-1000V

Safe, Accurate Voltage Testing in Your Pocket

This Intelligent Voltage Tester Pen provides fast, contact-free detection of live AC circuits, helping you work safely on outlets, switches, cables and appliances. Designed for professional electricians and serious DIY users, it combines non-contact voltage sensing, clear visual feedback and practical extras in one compact tool.

The tester detects AC voltage typically from 12V to 1000V (exact range may vary by model), allowing you to check low-voltage circuits as well as standard mains wiring. A built-in LCD display shows real-time voltage indication, while bright LEDs and an audible alarm signal the presence and relative strength of voltage. The integrated LED flashlight illuminates panels, junction boxes and tight spaces, improving visibility in low-light conditions. Powered by two AAA batteries, the pen is lightweight, ergonomic and easy to carry in a pocket or tool bag.

Use it to quickly identify live wires, trace circuit faults, verify power before maintenance and perform basic continuity checks. Auto/manual range selection supports reliable readings without complex setup, and the high-sensitivity sensor helps detect voltage fluctuations for more informed troubleshooting. Whether you are installing lighting, checking extension cords or verifying outlets on-site, this tester supports safer, more efficient electrical work.

Why It's a Smart Choice

• Non-contact safety - Detects AC voltage without touching bare conductors, reducing shock risk during testing.
• Clear visual and audible alerts - LCD indication, LED bar/indicator and buzzer make it easy to identify live circuits at a glance.
• Portable and versatile - Pen-style design, flashlight and wide voltage range make it suitable for home, workshop and jobsite use.
