YINUO YN-BD01 Whiteness Meter whiteness fluorescent whiteness opacity

Instrument use

YN-BB paper whiteness Tester is specially used for whiteness measurement of base paper materials in pulping, papermaking, packaging and printing industries. This Tester can accurately obtain whiteness values consistent with visual perception. For objects treated with optical brightener It can quantitatively reflect the whiteness value after fluorescent whitening, and can accurately measure the opacity and opacity of the paper to obtain the results. Widely used in the determination of paper, pulp, fiber pulp, textile, printing and dyeing, plastics, ceramics, food, building materials, paint, chemicals, salt, cement and talcum powder and other industries and commodity inspection departments that need to determine the whiteness of objects.

Features

1. Measure the blue light diffuse reflection factor (R457) of the sample, which is called blue light whiteness or ISO brightness (ISO Brightness);

2. Analyze whether the sample material contains fluorescent whitening agent, and measure the fluorescent whiteness produced by fluorescent reflection, that is, the whitening degree;

3. Measure the brightness stimulus value Y10 of the sample, that is, the green light diffuse reflection factor RY;

4. Determine the opacity, transparency, light scattering coefficient and light absorption coefficient of the sample;

5. Determination of ink absorption value of paper and cardboard;
