A level is a measuring tool that establishes a horizontal line of sight to determine the height difference between two points on the ground. Its main components include the telescope, tube level (or compensator), vertical axis, base, foot screw. According to the structure, the level is divided into micro-tilt level, automatic compensated level, laser level and digital level (also known as electronic level). According to accuracy, it can be divided into precision level and ordinary level. Automatic compensated instrument Automatic compensated level is a level that obtains horizontal sight line by means of automatic compensator.
