FIELD: measuring.
SUBSTANCE: invention relates to investigation of the level of environmental pollution, in particular to methods of determining content of oil products in wiping materials – in oily rags, which is a production waste during operation of vehicles, as well as other machines and factory equipment. Device for obtaining imprints of oiled rags in order to determine percentage content of mass of oil products. It comprises a hollow cylinder configured to accommodate the evaluated rags in its cavity and installed vertically on a sheet of paper with a substrate under it. In the cavity of the cylinder, above the rag, a pressure plate is installed, which is combined with a pusher, which has the possibility of axial movement along this cylinder and contact with the rag. Above the pusher there is a weight exerting a force effect on the rags. Besides, the lower part of the cylinder is placed in the bushing combined with the support ring.
EFFECT: simplified design and operation.
