Uni-T UT12D-Non Contact AC Voltage Detector, 24-1000V AC

Dual-Mode High/Low Voltage Sensing: Features selectable low-voltage mode (24V - 1000V AC) for low-voltage motors and irrigation systems, and standard high-voltage mode (90V - 1000V AC) for mains power circuits.

Audible & Visual Tri-Color LED Alert: Integrated buzzer with progressive sound frequency alongside synchronized green, yellow, and red LED indicators that intensify based on voltage field proximity.

Non-Contact Live/Neutral Wire Identification: Safely distinguishes between live and neutral wires without bare metal contact, reducing safety risks during electrical troubleshooting.

Built-in Bright LED Worklight: Equipped with a front-facing LED flashlight to clearly illuminate dark junction boxes, breaker panels, and outlet enclosures.

Integrated Breakpoint Location Tracking: Effortlessly traces insulated cable lines to detect hidden conductor breaks and circuit interruptions.

Auto Power-Off & Battery Saver: Built-in automatic power-saving shutoff feature powers down the device after 5 minutes of inactivity to preserveHere is a clear, professional product description ready to copy into your Shopify store for the Uni-T UT12D Non-Contact AC Voltage Detector:
