Preferably, the distance between the alignment scale and the level gauge is 100-500cm.
Preferably, the distances between the different alignment scales and the level meter are the same or different.
Preferably, the bottom of the level is provided with an adjusting foot.
Preferably, the laser beam emitted by the level meter comprises a horizontal beam and a vertical beam.
