Product Description
1. INTRODUCTION:
This is Whitness Tester
. Whitness Tester 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 2469, ISO 2470, ISO 2471, GB/T 7933, GB/T 7974, GB/T 8940.2, GB/T 1840, GB/T 2913, GB/T 13025.2, GB/T, 1543, ISO 2471, GB/T 10339, GB/T 5950 etc.
4. FEATURES:
1). Measure the Blue Reflectance Factor (R457) 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.
