As a precision color difference detection instrument, 3NH Colorimeter has its own specific detection standards for the production and application standards of different industries. The implementation standards of 3NH Colorimeter are the production standards followed by all walks of life. During the development stage of the instrument, 3NH’s R&D personnel consider these problems and directly set these rules inside the instrument.
Some implementation standards of 3NH Colorimeter are as follows:
GB 7973: Determination of diffuse reflectance factor of pulp, paper and cardboard (d/o).
GB 7974: Determination of whiteness of paper and board (d/o).
GB 7975: Determination of color of paper and board (d/o).
