Non-Contact Voltage Detector Tester
The Non-Contact Voltage Detector Tester is a pen‐style NCV tester that safely detects AC voltage from 12 V to 1000 V in cables, outlets, circuit breakers, and wires without physical contact. It offers dual-range sensitivity (12–1000 V AC and 48–1000 V AC) for versatile troubleshooting. A bright LED flashlight ensures visibility in low-light conditions, while the buzzer alarm and red LED alert you immediately upon voltage detection. The tester meets IEC safety standards (CAT III 1000 V / CAT IV 600 V) for professional use and features automatic shutoff after three minutes to conserve battery life.
