Non-Contact AC Voltage Tester | 12–1000V Live Wire & Breakpoint Detector

This non-contact AC voltage tester provides fast and reliable detection of live electrical circuits without direct contact. Designed for safety-focused inspections, it helps users identify live wires, locate circuit breakpoints, and verify electrical conditions before commencing work.

The integrated LCD screen displays real-time information such as voltage status, ambient temperature, and fault indicators. Adjustable sensitivity (High / Low) allows accurate detection across different environments, from low-voltage household wiring to higher-voltage electrical systems.

Built-in audible and visual alarms instantly alert users when live voltage is detected, while breakpoint detection helps pinpoint interruptions in single-strand wires. Additional features such as automatic power-off and a dual-mode flashlight enhance usability in low-light and extended inspection scenarios.

Compact and lightweight, this tester is well suited for everyday electrical troubleshooting, maintenance, and safety verification.
