Non-Contact Voltage Detector, Voltage Tester with Dual Sensitivity 12/48V-1000V, Phase/Neutral Wire Test, Sound & Light Buzzer, Flashlight, NCV Voltage Tester Pen

High Voltage Contactless Detection: This non-contact voltage tester detects AC voltage 12/48-1000V on household outlets, electrical cables and circuit breakers, perfect for home, electricians or quick interventions Immediate Visual and Sound Signal: Non-contact voltage detector LED indicator with three brightness levels (1-3 LEDs) and variable frequency buzzer, clearly indicating the voltage intensity. Brighter LEDs and faster buzzer indicate higher voltage or closeness to power source Phase and neutral identification: phase detector. Simply bring the probe close to a wire or outlet to distinguish the live wire (strong signal) from the neutral wire (weak/no signal). Facilitates cut-off detection and circuit inspection Built-in LED Flashlight & Auto Shut Off Function:Voltage tester, use the LED light at the end of the pen to illuminate dark work areas. The device will automatically shut off after 5 minutes of inactivity or in the absence of a signal, saving battery Compact and portable design: lightweight pen-shaped design, equipped with a clip for easy carrying. Powered by two AAA batteries (included)
