Levels are tools for measuring levelness and perpendicularity with the ground, and they include bubble levels. They are used mainly in locations where surveying is necessary, such as building construction sites and piping and electrical construction sites. Shapes include traditional angled type as well as round type with which measurements can be made in all directions, so a type that fits the location to measure and the application needs to be selected. Materials they are made of are acrylic or aluminum. There are digital types with more accurate display than bubble levels as well as levels with convenient functions such as laser beam and tape measure. There are also types with multiple bubble levels and scales attached to measure angles too, types with magnets incorporated in the main body to attach to the location to measure, and more.
