Voltage Tester/12V-300V Non-Contact and Contact Voltage Pen with NCV, Live/Null Wire Tester Electrical Tester with LCD Display Buzzer Alarm Wire Breakpoint Finder (More Accurate No Gloves)

【More Safety】CE CAT.II300V RoHS Certificate. No gloves are recommended during the test, Testing AC voltage needs the human body and ground wire to form a circuit. No Electric Shock Risk, No Dangerous, More Accurate Readings. The current flowing through the human body is less than 0.1uA. (Min current the human body sense：1mA). The internal circuit of the Voltage Pen is connected in series with a large resistor, which will burn out when the current is too large, and the circuit will disconnect. 【Alarm Mode】The buzzer and indicator light will be triggered when voltage is detected. High-frequency beeps means high voltage and live wire are detected. Low-frequency beeps sound mean low voltage and null wire are detected. 【Measurable Voltage】Equipped with a sturdy metal NCV probe for testing AC voltage; the test probe touches the conductor with AC voltage, and the voltage reading will show on display. To obtain more accurate values, it is recommended not to wear gloves when using. 【Multi-Function】Bright LED flashlight for work in dark areas; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket. 【Special Function】Can be used as a screwdriver for your convenience while working.
