Voltage Tester Pen, Voltage Detector Non-Contact Voltage Alert Sensor 90-1000V AC Socket Tester

Non-Contact Voltage Detection: Simply position the NCV tip near a terminal strip, outlet, or supply cord. When the tip glows red and the unit emits a beep, you'll easily confirm the presence of voltage Built-In LED Flashlight: Equipped with a convenient built-in flashlight, the Voltage Detector is designed to illuminate dimly lit workspaces, the bright LED flashlight features a backlight for enhanced visibility in low-light conditions, and the auto power-off function kicks in after 5 minutes of inactivity or when no signal is detected Compact and Durable Design: Featuring a pen hook for easy carrying in your shirt pocket, this voltage tester is crafted from high-quality engineering plastic. Its robust pen body is twice as thick as standard voltage testers, providing exceptional wear resistance and durability. The ergonomic industrial design guarantees insulation and comfortable handling Adjustable Sensitivity Settings: Effortlessly locating hidden lines and installing deeper wall outlets. This feature allows you to find the breakpoint of live wires by measuring changes in voltage strength Wide Voltage Detection Range: Capable of detecting voltages from 90-1000V AC, this versatile tester meets a wide array of needs across residential, commercial, and industrial settings. Electricians, maintenance personnel, safety officers, and homeowners can efficiently identify energized circuits and faulty grounds-whether on the factory floor, in the shop, or at home.
