Whiteness meter

Product Model : HM-3148
The whiteness tester is used to measure the whiteness of objects. It is widely used in paper-making, textile, printing and dyeing, plastics, ceramics, enamel, grain, building materials, paint, chemical industry, salt and other production and commodity inspection departments that need to measure the whiteness of objects. The instrument can also measure the ISO brightness (ISO Brightness, namely R457 whiteness). For fluorescent whitening samples, it can measure the fluorescent whitening degree produced by the emission of fluorescent substances, and can measure the transparency of paper and other thin sheet materials. No Transparency. Light scattering coefficient and absorption coefficient, etc.
