# Device for determining the inclination of a plane with respect to theoretical horizontal plane

## 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.
