Whiteness meter is used to measure the whiteness of objects. It is widely used in paper making, textile, printing and dyeing, plastics, ceramics, enamel, food, building materials, paint, chemical industry, salt and other production and commodity inspection departments that need to measure the whiteness of special bodies.The whiteness meter can measure the paper's transparency, opacity, light scattering coefficient and absorption coefficient.The whiteness meter complies with GB3978-83: Standard Illumination Body and Illumination Observation Conditions.Simulate D65 lighting body lighting.D/O illumination is used to observe the geometrical conditions (ISO2469). The diameter of the diffuse ball is φ150mm, and the light absorber is equipped to eliminate the influence of the light reflected by the sample mirror.The spectral power distribution of R457 whiteness optical system has a peak wave of 457nm and a half-height width of 44nm.RY optical system conforms to GB3979-83: method of measuring color of objects.
