The invention is related to the field of machinery and apparatus construction, as well as to metrology. Application is mainly related to investigation slip properties of friction pair metal-ice, but it can equally be applied for investigation of slip properties of other materials on a variety of substrate materials, i.e. polymer-ice, metal-metal, etc. The invented device shown in Fig.1 consists of a rack (1), inclined plane (2), angle adjustment unit (3) shown in Fig.3, optical sensors (5), locking units (6) of inclined plane, and sample capture/activation units (7). The invention allows to perform measurements with minimal involvement of operator. The invented measurement method provides the following information about investigated sample (17): sliding time of the overall distance, sliding times for all distances between optical sensors (5) and instantaneous sliding speed for at least four overall distance stages.
