Whiteness Analyzer is used for measuring the surface blue light whiteness of different objects, the measure result is digital displayed and could be printed out by the inner printer (Optional function). The Analyzer is easy to operate and has a high measurement precision. It could be used for the whiteness measurement of different materials and industries, e.g. flour, amylum, rice flour, salt, textile, printing and dyeing, chemical fiber, plastic, porcelain clay, talcum powder, white cement, dope, paint, chine, ceramic, porcelain enamel, paper sheet, paper pulp.
★ The instrument is equipped with a long-life light source, which is energy-saving and environmentally friendly.
★ Fully sealed design to meet various production site measurements.
★ The intelligent whiteness tester adopts a simple linear calculation method with high accuracy.
★ Easy and convenient operation, one click zero calibration, stable and reliable.
★ Highly integrated hardware design, embedded operating system. Fast digital wave algorithm, complete the measurement in two seconds.

Diffuse illumination and vertical sounding method(d/o), simulation D65 illuminant use d/o illuminating viewing and geometrical condition. Globe of diffusion diameter is 120.Measuring whole diameter is 20 mm. Have light absorber, can eliminate reflected ray of sample mirror surface.
Working Principle.
The instrument achieves the absolute spectrum diffuse reflection measurement by the integral ball. The optic principle is shown in Figure above. Light was emitted from halogen tungsten light (1), the beam turn to blue purple light through the light aggregation mirror(2) and the light sieve sheet(3), then the light which entered the integral ball(4) would be diffuse reflected by the inner wall and irradiated on the sample in the examination hole(5), through the light aggregation mirror(6), light column(7) and the light sieve sheet group (8), the light which is reflected by the sample would be absorbed by the silicon photocell (9) and be turned to electric signal. The fundus signal of the integral ball was absorbed by the other line of silicon electric eye. Two lines of electric signal would be amplified separately and treated at the same time. The measure result would be digital displayed, and could be printed by the inner printer(Optional function).
