Non-Contact Voltage Detector Pen – Smart AC Voltage Tester & Breakpoint Finder, 12–1000V

Check for the presence of AC voltage quickly and conveniently with this Non-Contact Voltage Detector Pen. Designed for electrical troubleshooting and circuit maintenance, it detects alternating current without requiring direct contact with exposed wires.

Its adjustable sensitivity ranges, visual LED alerts, and built-in illumination make it a practical tool for identifying energized wires and locating potential breaks in AC wiring.

Key Features

• Non-Contact Detection — Detects AC voltage without directly touching the conductor.

• Wide Detection Range — Supports AC voltage detection from 12–1000V in high-sensitivity mode and 48–1000V in low-sensitivity mode.

• Adjustable Sensitivity — High and low sensitivity modes help detect voltage at different distances.

• Visual Alerts — LED indicators provide visual warnings when AC voltage is detected.

• Live Wire Identification — Helps distinguish stronger live-wire signals from weaker or neutral-wire signals.

• Built-In Flashlight — Integrated illumination helps provide visibility when working in darker areas.

• Portable Pen Design — Compact and easy to carry in a toolbox, pocket, or electrical kit.

• Automatic Proximity Response — Alarm intensity can increase as the tester moves closer to a detected AC source.

Important Safety Information

• This tester is designed for AC voltage detection only and does not detect DC voltage.

• Always follow appropriate electrical safety procedures.

• Do not exceed the product's rated voltage.

• A non-contact voltage detector should not be considered the sole method of verifying that a circuit is de-energized. Always use appropriate testing procedures and equipment when performing electrical work.

• Use only 1.5V AAA batteries. Do not substitute lithium batteries with a higher voltage.
