FIELD: physics; measurement.
SUBSTANCE: level containing laser source, ring base including cantilever; case through the hole formed from its one side, tripod-borne rigidly connected to platform, from the other side the case includes two opposite angular through openings and one horizontal through cut. The level contains measuring scales, the first scale is supported. Two measuring scales are mounted on straight portion of the cantilever. Invention refers to construction and can be used for vertical and horizontal surfacing operations prior to plastering, flooring, etc. Invention meets the challenges as follows: improved performance of level due to possibility to use it for surface verticality and perpendicularity testing, as well as for testing of surface horizontal position. Besides declared level can be applied for vertical, horizontal and angular surfacing operations.
EFFECT: improved performance of level.
