ISO brightness tester-whiteness meter for porcelain,rice,salt also powder - DRK103A

ISO brightness tester-whiteness meter for porcelain,rice,salt also powder

The tester is used to test the whiteness. It also can test the paper’s transparency, opacity, light scattering coefficient and light absorption coefficient, also can define printing ink absorption values of paper and cardboard. The meter can menstruate many times and gives series of arithmetic measuring result. The testing data will store while powering off for a long time.

Standard and Character

The tester is designed according to GB3978-83(standard lighting substance and lighting observing condition, modeling D65 lighting. It adopts d/o lighting observing geometry terms (ISO2469), ISO2470 (ISO brightness), ISO2471(Opacity),etc. The diffuse diameter is 150mm. It uses light absorber to eliminate the influence caused by the specimen’s mirror reflecting light.

Field

brightness tester is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, chemical industry, Salt Making and other testing department that need to test whiteness.
