Introducing our advanced Multifunctional Tool, perfect for various applications including electrical testing and car repair. This compact device combines several essential features: NCV AC Voltage Detection: Perform non-contact AC voltage detection effortlessly. This tool also offers the convenience of inserting the tester's probe directly into power outlets, accompanied by an alarm buzzer. Built-in LED Flashlight: Enhance your safety and visibility while working in dark environments. Dual Range AC Voltage Detection: Choose between low sensitivity mode (48~1000V) and high sensitivity mode (12~1000V). Start with low sensitivity for better accuracy, especially when locating live wires. Live/Neutral Wire Discrimination: Easily distinguish between live and neutral wires based on detection strength. Strong induction indicates a live wire, while a weak or absent signal indicates a neutral wire. Ambient Temperature Tester: Measure the temperature of the surrounding environment with ease. Temperature units can be displayed in either °C or °F. Easy-to-read LCD Screen: The large display improves your reading experience, making information clear at a glance. Compact and Portable: The lightweight design and one-handed operation make it a convenient tool to carry and use anywhere. Long-Lasting Power: Powered by 2 AAA batteries (not included), with automatic shutdown after 5 minutes of inactivity to conserve battery life. Low battery is indicated on the display. Important Notes: Please read the user manual thoroughly before operating the device. Product size and color may vary slightly due to manual measurement and lighting conditions.
