  • SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected
  • NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners

  • NCV: The Non-Contact Voltage Tester is equipped with NCV sensing probe, which provides you with the easiest and safest way to check the voltage in a wire, outlet, or switch. When it is close to an outlet or power cord, the voltage detector will emit different levels of alarm sounds and signal indicator lights to indicate the presence and strength of voltage
  • 3 Sensitivity Modes: The live wire tester suits different voltage detection ranges. After powering on, it is in low sensitivity mode by default (buzzer 1 time), press "S" once to enter medium sensitivity mode (buzzer 2 times), and press "S" again to enter high sensitivity mode (buzzer 3 times)
