Spirit or vapour level structure for workshops and similar, consisting of an elongated case and a clear tube, containing the liquid, arched in its middle section for bubble formation. The level includes a rectilinear prismatic case with a flat base and a clear tube, either arched or with a wide-radius toric hollow so as to allow the formation of a bubble that can translate from its centred position to the opposite ends of said tube. Starting from the opposite edges of the centred bubble, the tube is equipped with a pre-set scale numbered from 0 to 90 DEG , in order to allow the user of a machine tool (drill, mandrel, planer, miller or similar) to quickly identify and check at any moment, after positioning the level on one or on all faces of the machine body, the degree of inclination of the plane on which the level is positioned. |
