Non-Contact AC Voltage Tester

Stay safe while working around electricity with this Non-Contact AC Voltage Tester, a handy pen-style indicator designed to quickly detect live AC voltage without touching exposed conductors. It’s an essential tool for electricians, technicians, maintenance workers, and home users who want a fast way to confirm whether power is present before handling sockets, switches, cables, or appliances.

With a 12–1000V AC detection range, this tester is suitable for everyday electrical work—checking wall outlets, extension cords, lighting circuits, breaker panels, and power lines. Once it senses AC voltage, it alerts you using a buzzer sound and LED light, helping you identify live wires instantly. The integrated flashlight makes it easy to inspect wiring in poorly lit spaces such as ceilings, meter boxes, and behind furniture.

It also supports intelligent breakpoint detection, which can help you trace wiring and locate possible breaks or fault points—useful for troubleshooting power loss and identifying damaged lines. The compact body and pocket clip make it convenient to carry anywhere, and the simple controls make it easy to use even for beginners.

Note: This is an AC voltage detector (non-contact). It is used for identifying live AC voltage presence and basic fault tracing.
