GOTOTOP NCV Voltage Tester Pen with Flashlight and Soundlight Supply, LCD Screen Voltage Pen for Electricians

1. [Wide Range] This voltage tester pen can accurately detect the AC voltage from 12V to 300V, meets various needs of electrical testing, which ensures that it can be used in residential and commercial environments. 2. [NCV Sensing] When the test pen probe approaches the AC voltage source, the ringer emits a sound; the frequency of the ringer is divided into three levels, increasing with the signal resistance. At the same time, the display screen will show U or HI when the signal strength is strong, allowing you to search for breakpoints. 3. [Flashlight & LCD Display] The built-in flashlight can illuminate dark areas, while the backlit LCD display shows clear readings, improving visibility. The flashlight and transparent LCD display combine to ensure you can work in low light conditions and easily read test results. 4. [Sound and Light Request] When the probe touches the live wires, the screen is displayed in HI with red backlight and the doorbell emits a fast beep sound. The immediate double provides visual and auditory warnings, improving safety. 5. [Dual-use Screwdriver Head] Detachable dual-use screwdriver head meets electrical testing and adjustment requirements, allowing you to multitask, convenient and space saving.
