WSB－2whiteness meterUsed to determine the whiteness of objects, it is widely used in papermaking, textile, printing and dyeing, plastics, ceramics, enamel, grain, paint, chemical, salt and other production and inspection departments that require the determination of specific whiteness. The instrument can also measure the transparency, opacity, light scattering coefficient, and absorption coefficient of paper.

Standard lighting fixtures and lighting observation conditions. Simulate D65 illumination body lighting. Using d/o illumination to observe geometric conditions (ISO2469), the diameter of the diffuser sphere is 150mm, and a light absorber is installed to eliminate the influence of specular reflection of the sample. The peak wavelength of the spectral power distribution of R457 whiteness optical system is 457nm, with a full width at half maximum of 44nm; The RY optical system complies with GB3979-83: Methods for measuring object color. It is possible to measure multiple times and provide the arithmetic mean of a series of measurement results. Equipped with power-off protection, zero adjustment, calibration, and standard measurement data

Product UsageIt is mainly suitable for measuring the whiteness of objects or powders with flat non colored surfaces, and can accurately obtain whiteness values consistent with visual sensitivity. For objects treated with fluorescent whitening agents, the whiteness value after fluorescence enhancement can be quantitatively reflected. It can be widely used for measuring the whiteness of substances such as textile printing and dyeing, paint and coatings, chemical building materials, paper and cardboard, plastic products, white cement, ceramics, enamel, talcum powder, starch, flour, salt, detergents, cosmetics, etc.

Product Features:

1. Equipped with imported original components, high-efficiency, low loss switching power supply, and good reliability

2. Reasonable and concise optical path design, using a modified color filter system, can quantitatively reflect the whiteness value after fluorescent whitening

3. A reliable activity platform design can effectively avoid the phenomenon of light leakage at the measurement aperture

4. Simple operation, can accurately measure the opacity of paper

5. Use national calibration whiteboards to transmit standard values, ensuring accurate and reliable measurement
