OPENTECHNICAL PUBLICATION OT-2026-000003456 Device for determining the inclination of a plane with respect to theoretical horizontal plane Published: 2026-09-15T20:29:41.660007Z Permanent URL: https://opentechnical.org/p/OT-2026-000003456 Categories: Tools & Tooling > Clamping Tools ------------------------------------------------------------------------ ABSTRACT The present invention relates to a device for determining the inclination of a plane with respect to a theoretical horizontal plane, including a box-like body defining a base plane. An inclination detector element is rotatably associated with the box-like body; light detectors determine the position of the detector element with respect to the base plane; a display indicates the inclination of the base plane relatively to a theoretical horizontal plane. The light detector and the display are powered by batteries and operated by a switch. 1.
