Description
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
specimen，as 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; it can do test 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 D*5 lighting
engineering and adopts CIE***4 complementary color system and
CIE***6（L*a*b*）color
space chromatism formula.
2．It adopts d/o lighting observing geometry terms
(ISO***9,ISO***0,ISO***1). The diffuse diameter is **0mm and the
test hole diameter is *5mm. It uses light absorber to eliminate the
influence caused by the specimen’s mirror reflecting
light.
