摘要：The granulometer uses a measuring laser beam (9) to illuminate particulate and,through the measure of the distribution of the light diffused by the examined particulateand gathered by a collecting lens (11), measures the concentration of particulate in thefluid in low concentration standards, the laser beam (9) being a converging one focusedon a laser opaque shell (12) that partly covers the same lens.
