DRK103B Brightness and Color Tester
The meter is widely applied in papermaking,、fabric, printing,
plastic, ceramic and porcelain enamel, construction material,
chemical industry, salt making and other testing department. It is
used to test the whiteness, yellowness, color and chromatism of
specimenas well as transparency, opacity, light scattering
coefficient and light absorption coefficient of paper.
Characters:
Reference can be practicality or data; The meter can maximum store
ten references’ information; Menstruate many times and give series
of arithmetic measuring result; Digital display and the result can
be printed out; The testing data will be stored while powering off
for a long time.
Technical data:
1.It simulates D65 lighting engineering and adopts CIE1964
complementary color system and CIE1976(L*a*b*)color space
chromatism formula.
2.It adopts d/o lighting observing geometry terms (ISO2469). The
diffuse diameter is 150mm and the test hole diameter is 25mm. It
uses light absorber to eliminate the influence caused by the
specimen’s mirror reflecting light.
