This digital test pen features a pen-shaped body with a pointed metal tip, black front panels, and a built-in display window for clear voltage reading. As an NCV test pen, it supports non-contact sensing for live-wire identification, helping you check for AC voltage presence without direct contact. It is designed for voltage measurement, continuity checking, circuit-break detection, and leakage-voltage detection in everyday electrical work. The test pen provides sound and light alarm indication, making detection results easier to notice in brighter or noisier environments. With its compact pen-style form and button controls on the body, it is suited to quick checks on wiring, outlets, and circuit points where fast verification is needed.
