Description
1.
INTRODUCTION:
1). Make measurement of colour and colour difference reflected by
materials.
2). Make measurement of ISO brightness (Blue Whiteness R**7) and
degree of whiteness for Fluorescent whitener.
3). Make measurement of CIE whiteness (Ganz whiteness W*0 and Color
cast value Tw*0) Make measurement of whiteness of building
materials and non-metallic minerals.
4). Make measurement of Hunter system Lab and Hunter (Lab)
whiteness reflectance factor.
5). Make measurement of yellowness.
6). Make measurement of opacity, transparency, light scattering
coefficient and light absorbing coefficient.
7). Make measurement of ink absorption.
2.
APPLICATIONS:
Paper, Board, Pulps, Chemical fiber, Textile, Plastic, Ceramic,
Enamel, Fecula, Salt, White cerement, Porcelain clay and French
chalk etc
3.
STANDARDS:
ISO ***9, ISO ***0, ISO ***1
4.
SPECIFICATIONS:
1). Repeatability of test: δ(Y*0)< 0.1, δ(X*0, Y*0)<
0.**1
2). Accuracy
: ?Y*0<
1.0,?x*0(Y*0)< 0.*1
3). Sample size: Diameter of the testing plane should be larger
than *0mm while the thickness larger than *0mm.
4). Power supply: **0~**0V, *0Hz, 0.3A
5.
FEATURES:
1). Simulate D*5 illuminator to illuminate. Adopt CIE ***4
supplementary standard colorimetric system and CIE ***6(L*a*b)
colour space and colour difference formula.
2). Adopt d/o illuminating*-geometrical viewing conditions.
Diameter of the globe of diffusion is **0mm and diameter of the
testing hole is *5mm. Light absorber is provide to eliminate the
effect of mirror reflection.
