This is High quality brightness Tester PN-48B .
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.

Paper, Board, Pulps, Chemical fiber, Textile, Plastic, Ceramic, Enamel, Fecula, Salt, White cerement, Porcelain clay and French chalk etc.

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.
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.

1 This instrument complies with GB3978-83; Standard illuminator and illuminating--viewing conditions.
2 Simulate D65 illuminator to illuminate. Adopt d/o illuminating--viewing geometrical coanditions. Diameter of the diffusion sphere is 150mm and diameter of the testing hole is 25mm.
3 Light absorber is provided to eliminate the effect of specular reflection. Peak wavelength of spectral power distribution of R457 whiteness optical system is 457nm and its half-width is 44nm.
4 Measure and display the whiteness, Fluorescent whiteness (whitening rate) and opacity (%) etc. digitally.
5 Indication error: 0.50%

Our products are rigorous in manufacturing, high quality and reliable in operation. Our products are exported to many countries and are well received by users. We off OEM services to global customers and we can manufacture slurry pumps or spare parts according to the construction drawings and samples. The parts can be made of nonmetallic materials, include:

1.rubber materials

The rubber materials are suitable for conveying abrasive slurry or corrosive slurry without sharp particles (such as river sand) or fine particles (d<0.5mm).

2.Polyurethane elastomeric materials

The polyurethane elastomer materials have physical dynamic properties similar to rubber, but have better wear resistance than rubber, especially in working conditions of wet media such as water and oil, and their wear resistance is usually several times better than ordinary rubber materials.
