What is the level used for?

The height difference between ground points is measured according to the leveling principle.

The main components are telescope, pipe level (or compensator), vertical shaft, base and anchor screw. According to the structure, it is divided into micro-tilt level, automatic level, laser level and digital level (also known as electronic level). According to the accuracy, it is divided into precision level and ordinary level.

17 ~ 18 century after the invention of telescope and level, level appeared. At the beginning of the 20th century, the micro-tilt level was produced on the basis of the internal focusing telescope and the level. In the early 1950s, automatic leveling level appeared. Laser levels was developed in the 1960s; Electronic level or digital level appeared in the 1990s.
