1. INTRODUCTION:
brightness meter, brightness tester, whitenss meter, whiteness tester. The brightness meter is mainly 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, GB/T ***3, GB/T ***4, GB/T ***0.2, GB/T ***0, GB/T ***3, GB/T ****5.2, GB/T, ***3, ISO ***1, GB/T ****9, GB/T ***0 Etc.
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
9). Working condition:Temp.***0oC, relative humidity *0). Size and weight: L×W×H=**5×**0×**5mm, *1kg
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.
