The UltraScan VIS spectrophotometer measures both reflected and transmitted color, and meets CIE and ASTM guidelines. As recommended by the CIE, spectral data is measured, and tristimulus color calculations are performed, from 360 nm to 780 nm. Its light source is controlled in the ultraviolet region for the accurate measurement of whitening agents. APHA, Saybolt, Gardner, ASTM D 1500, Yellowness, Whiteness and Haze can be measured. The system's sphere geometry virtually eliminates errors introduced by sample haze.
