Ingco Non-Contact AC Voltage Detector | 12V–1000V Dual Sensitivity Pen Tester with LED Flashlight & Audio Alarm (VD10003)

The Ingco VD10003 Non-Contact AC Voltage Detector is an essential, pocket-sized electrical safety tool engineered to safely sense the presence of AC voltage without requiring direct contact with bare, live conductors. Designed for electricians, maintenance technicians, and DIY homeowners, this pen-style tester allows you to quickly check electrical outlets, lighting fixtures, circuit breakers, and wiring paths for live current before initiating installation or repair work.

The device features an intelligent dual-sensitivity detection system, allowing it to seamlessly switch ranges to isolate voltage across various systems. When placed near an active alternating current field, the tester delivers clear, multi-sensory feedback via a bright, flashing red LED indicator tip and an audible beeper tone. The frequency of the flashes and beeps increases proportionally as you move closer to the live voltage source, making it simple to pinpoint hidden line breaks or trace wire runs behind drywall. For added utility in dark workspaces, electrical panels, or deep junction boxes, the device is equipped with an integrated forward-facing LED flashlight. Constructed with a durable, fully insulated ABS housing and a convenient pocket shirt clip, it offers a high safety rating for ultimate peace of mind on the job.
