  • Non Contact: Just place the NCV 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 Tests. Handy circuit tester for electricians, and homeowners.
  • 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. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected.
  • Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.
  • Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen.
