Voltage Testing Pen

Voltage Testing Pen An AC voltage tester pen is a handheld, non-contact device used to detect the presence of AC voltage in electrical circuits without making direct contact with wires or terminals. The model shown in the image includes an LED auxiliary lighting lamp and an inductive alarm for enhanced usability. Key Features Non-contact detection: Uses an induction probe to sense AC voltage without touching bare conductors. LED auxiliary lighting: Helps illuminate dark work areas. Inductive alarm detection: Emits sound and light alerts when voltage is detected. Flashlight switch: Turns the LED light on or off. Boot button: Powers the device on. Compact design: Approximately 152.5 mm (6 inches) in length, easy to carry. How It Works Power On: Press the boot button to activate the tester. Test for Voltage: Bring the induction probe close to the wire, socket, or electrical outlet. Detection: If AC voltage is present, the LED will light up and the alarm will sound. Safety: Always test the pen on a known live source before and after use to ensure it is functioning correctly. Applications Checking wall outlets for live voltage. Identifying live wires in cables. Troubleshooting electrical circuits safely.
