Product Overview 

 -------------------------------------------------- ------------------------------ 

 ZB-B whiteness meter is the whiteness of special instruments, the determination of the object. Widely used in paper, cardboard, textile dyeing, paint and coatings, chemicals, building materials, plastic products, cement, calcium carbonate powder, ceramic, enamel, porcelain clay, talc, starch, flour, salt, detergents, cosmetics and other objects for measurement of whiteness. 
 Instrument specific functions are as follows: 
 1 Determination of whiteness (ISO the Brightness, whiteness (R457)), fluorescent whitening of the specimen, but also can determine the fluorescent material emission generated by the fluorescent whitening. 
 The determination of the brightness stimulus value. 
 (3) determination of opacity. 
 4 Determination of transparency. 
 Determination of light scattering coefficient and absorption coefficient. 
 Measuring ink absorption value. 
 Implementation of standards
