Flycross Non-Contact Voltage Detector Electric Power Socket Outlet AC Voltage Tester Pen Digital Battery Tester

[Dual mode]: This detector has automatic/manual dual mode to choose from according to your needs. It is convenient to detect and report the presence of AC voltage in automatic mode, or applied multiple times in manual mode. [Adjustable sensitivity]: The sensitivity of the voltage detector is adjusted to any value according to your requirements. Low sensitivity for more accuracy at distinguishing complex lines; High sensitivity for easier finding hidden lines and installing deeper wall outlets. [8 LED Indicators In 3 Colors]:The voltage tester pen features 8 LED indicators in 3 colours (2 green, 3 yellow and 3 red), triple buzzer alarm.The voltage strength can be easily and visually determined by the different coloured LEDs that light up and the alarms of different frequencies. [Live Wire Tester]: Safe and easy to distinguish the live wire by judging the strength of the detected voltage, the line with the stronger voltage signal is live wire. [Breakpoint Finder]: Find the breakpoint of the live line by measuring the change of voltage strength in the live wire.
