【Scope of application】
It is mainly used for whiteness measurement of objects or powders with flat non-color surfaces, and can directly measure the optical properties of objects such as whiteness, brightness, transparency, opacity, light scattering coefficient, and light absorption coefficient. For objects after fluorescence whitening, not only the whiteness value consistent with the vision can be measured, but also the fluorescence whitening effect - whitening value can be measured.
【Relevant Standards】
JB/T9327-1999 "Whiteness" standard, JJG512-2002 (whitenessmeter) first-class instrument requirements.
