INTRODUCTION:
The tester is used to test the whiteness of diversified
objects such as paper and board, pulps and chemical fiber, textile,
plastic, ceramic, enamel, fecula, salt, white cerement, porcelain
clay and French chalk, etc. It can also be used to test the optical
performance of sheet materials, for example, opacity test.
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). This instrument complies with GB******3; Standard illuminator
and illuminating*-viewing conditions.
2). Simulate D*5 illuminator to illuminate. Adopt d/o
illuminating*-viewing geometrical coanditions. Diameter of the
diffusion sphere is **0mm and diameter of the testing hole is
*5mm.
3). Light absorber is provided to eliminate the effect of specular
reflection. Peak wavelength of spectral power distribution of R**7
whiteness optical system is **7nm and its half-width is *4nm.
4). Measure and display the whiteness, Fluorescent whiteness
(whitening rate) and opacity (%) etc. digitally.
5). Indication error: 0.5%
6). Sample size: Test plate diameter should not be less than *0mm
while sample thickness should not exceed *0mm.
7). Power supply: **0V***0V, *0Hz, 0.3A
8). Measure time: 3s
5.
FEATURES:
1). Measure the Blue Reflectance Factor (R**7) of samples. Blue
Reflectance Factor is so called “Blue Whiteness” or “ISO
Brightness”.
2). Analyze the sample to find out whether it contains any
fluorescent brightener. If so, measure the fluorescent whiteness
further, namely whitening rate.
3). Measure the opacity, transparency, light scattering coefficient
and light absorbing coefficient.
