A Level, which becomes widespread worldwide today, originally came from Europe. People established a standard of a level through they dug groove and pool water in it in ancient time.
A level has high valuation, which were made up and improved, in long history by an old craftsman finding that water was flat.
The level is a thing finished up in the tool that predecessors’ workmen discover the thing with flat water it is polished up by a long history and value is high.
Structure of a level suits this principle. A level with vial is made up by utilizing a principle that surface of liquid always attempt to be flat. A pointer type of level is made up by utilizing a principle, “when weight affects to the way of gravity, the pointer will stop.”
|Level with vials||A level with vials shows the horizontal, the vertical, and/or gradients when the bubble reaches the midpoint of the benchmark.Frame is made with aluminum and/or resin.|
|Pointer type of level||A pointer shows the horizontal, the vertical, and/or gradients when the axis of the pointer revolves and affects toward gravity. A weight is fitted on the other side of the pointer.|
|Laser level||Check the horizontal reference plane by using a vial first, and then ensure the level so that laser light is irradiated horizontally and/or vertically toward this surface.You can verify the horizontal line and/or the vertical line with your eyes.|
