Non-Contact Voltage Adjustable Tester

This voltage test pen is equipped with an advanced NCV (Non-Contact Voltage) sensor that allows you to safely detect AC voltage without direct contact. Simply press the power button and place the probe near a power outlet, wire, or live line to identify voltage presence quickly and easily. When AC voltage is detected, the indicator light flashes to alert you. The tester displays different signal strength levels using coloured indicator lights—two red lights for high voltage, two green lights for medium voltage, and one green light for low voltage—while the built-in buzzer provides distinct audible alarms for each level. Designed for convenience and safety, this tester also features a built-in LED flashlight, making it ideal for use in dark areas or during emergencies as a portable light source.
