Введение:Brightness Meter is widely applied in paper and cardboard, мякоть, cotton and fabric, пластик, ceramic and porcelain enamel, amylum, construction material, химическая индустрия, salt making and other testing department that need to test whiteness.
Функция:
- Test R457 or ISO Brightness
- Analysis if it contains fluorescent whitening agent and determination of reflection fluorescence produced by white fluorescent, то есть, degree of whitening
- Test the brightness value of Y10, то есть, the green light diffuse reflectance factor Ry.
- Test the non-transparency, прозрачность, light scattering and light absorption coefficient
- Test the ink absorption value of paper and board.
Технические данные:
The diffuse diameter is 150mm and Test whole diameter is 30mm. It uses light absorber to eliminate the influence caused by the specimen’s mirror reflecting light. R457 whiteness optical spectral power distribution system in the peak wavelength 457nm, FWHM 44nm, Y10 optical system in line with the GB3979-83; object color measurement.
Test and digital show the value of whiteness, флуоресценция (отбеливание) яркость, непрозрачность (%).
