Paper Brightness Whiteness Opacity Tester GT-N04B
Paper Brightness Whiteness Opacity Tester GT-N04B
Application
This paper brightness tester is designed for measuring the whiteness, yellowness, hue, and color difference of materials across various industries, including paper manufacturing, printing, textile dyeing, ceramic and enamel production, building materials, chemicals, food processing, and salt production. Additionally, it evaluates paper properties such as opacity, transparency, light scattering coefficient, light absorption coefficient, and ink absorbency.
