Measurement Tools

Surveying equipment are instruments for measuring the size and distance of land. There are various devices depending on the object to be measured such as the auto level to check the level and height of the land, theodolite to measure the angle, laser distance meter and measuring wheel to measure the distance, down swing to check whether the wall or pillar is vertical, the crack gauge to measure the size of cracks on the wall, etc. For convenience, digital inclinometers are increasingly used instead of analog level quarters and slant rules. Architectural markers, inkpots, mason’s lines, etc. for keeping the reference point constant have waterproof ones and can be used without being affected by the weather. Because they are often used outside, there are many all-weather models, and most models use durable and lightweight materials such as aluminum.
