PURPOSE:To make it always possible to measure exactly the degree of grain polishing by installing a cleaner at the tip end of a measurement rod that is provided in the detection section chamber of a grain polishing measurement device with free entrance and exit and removing attached objects with the cleaner every time the measurement is made. CONSTITUTION:On the right side of an integration ball 1 a detection chamber 2 in which specimens flow and a light-receiving element 8 for light that passes through are provided, and below the ball 1 a light-receiving element 8' for reflected light, and on the left side a light source device that consists of a light source lamp 4, etc. Both wall faces of the chamber 2 are formed with quartz glass 18 and a measurement rod 20 at the tip end of which a cleaner 19 is provided is installed with free entrance into and exit from the chamber 2. When the degree of polishing is measured, the measurement rod 20 is inserted by a driving motor 23 and attached objects are cleaned by the cleaner 19, then a standard white plate 22 is inserted to set up the standard polishing by light-receiving elements 8 and 8'. Next, the degree of polishing is measured by means of a specified circuit. Accordingly, everytime the measurement is made, attached objects are removed, and the degree of polishing can be exactly measured. |
