The whiteness meter is a professional instrument dedicated to the determination of the whiteness of samples. It is widely used in flour production and quality testing. The application of this instrument realizes the quantification of flour whiteness and is more helpful to the optimization and improvement of flour quality. When designing the meter, what are the reference standards? Here is a brief introduction. The whiteness meter meets the standard: GB/T 7933-87 Pulp, paper and cardboard diffuse reflectance factor measurement method (d/o method) From this we can see that the whiteness meter has a wide range of applications, not only for the determination of flour whiteness, but also for measuring paper and cardboard, pulp and chemical fiber pulp, cotton and chemical fiber, textiles, plastics, ceramics, and porcelain , Starch, salt, white cement, china clay, talcum powder and other objects.
