Electrical Tester, Non-Contact Voltage Detector 12-1000V, Live/Neutral Wire Test, Audible & Visual Buzzer, Flashlight, AC 50-500Hz, NCV Voltage Tester Pen

General Description This non-contact electrical tester is designed to detect voltages from 12V to 1000V, classifying them into three voltage categories. It is equipped with an audible buzzer and a visual indicator to alert the user to the presence of voltage. The device is ideal for safe use, allowing you to measure voltage without needing a professional electrician. Technical Specifications Detectable Voltage: 12V - 1000V Frequency: AC 50-500Hz Voltage Indication: On-screen display Safety: Non-contact testing Insulated pen body for increased safety Flashing and audible alarm in the presence of AC voltage Usage The The tester beeps and flashes when the device is near an alternating voltage, allowing for quick and efficient detection. If the red LED flashes rapidly, this indicates the presence of a live wire, while a solid red LED means that the zero line is detected.
