Dual Range AC Voltage Detection: Detects both low (121000V) and high (481000V) AC voltage levels, making it ideal for a wide range of residential, commercial, and industrial applications. Easily switch between sensitivity modes with the touch of a button to suit your testing needs. Safe & Non-Contact Voltage Testing: No direct wire contact neededsimply bring the NCV probe close to outlets, wires, or terminals. A red light and audible buzzer will immediately alert you to the presence of live voltage, helping you stay safe while working. LCD Display with Smart Visual & Audio Alerts: The clear LCD screen displays voltage status with intuitive color-coded feedback: red screen for high voltage/live wire, green for low voltage/null wire. The beeping frequency increases as you get closer to the voltage source for precise detection. Built-In LED Flashlight & Automatic Shut-Off: Work safely in dimly lit or hard-to-reach areas using the bright built-in LED flashlight. The tester automatically po
