Digital levels are electronic tools used to measure the angle of a surface relative to the horizontal or vertical plane. They utilize sensors to detect tilt and display the information on a digital screen, making it easier for users to achieve precise leveling. These devices are commonly used in construction, carpentry, and other fields where accurate measurements are essential. Unlike traditional bubble levels, which rely on a liquid-filled vial, digital levels provide numerical readings and often include features like audio alerts when the surface is level. Many models also offer additional functions, such as memory storage and the ability to measure angles in degrees or percent slope, enhancing their versatility in various applications.
