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

General description This Electrical Tester is a non-contact voltage detector designed to measure voltages ranging from 12V to 1000V. It can distinguish between three voltage classes and features both sound and light indicators to alert users to the voltage intensity detected. Technical specifications Voltage detection range: 12V-1000V Frequency: AC 50-500Hz Usage Detects voltage without direct contact, ensuring user safety. Flashes and beeps when near AC voltage. Indicates low, medium, or high sensitivity with different frequencies and LED color differences. Red LED flashes rapidly with an alarm when a live wire is detected; steady when a neutral line is detected. Other information Insulated pen body for added safety.
