RH-48B Brightness Meter<\/h1>\n

<\/h2>\n

Introduction<\/b><\/strong>:<\/b><\/strong><\/span><\/h4>\n
\n

RH-48B Brightness Meter is mainly used to measure the whiteness of paper, paperboard, paper pulps, pulps of chemical fiber, cotton, chemical fiber, textile, plastic, starch, salt, white cement, porcelain clay and talcum powder, etc. It can also be used to measure the opacity and other optical performance of thin pages.<\/p>\n

\n
\n

1. Measure the diffuse blue reflectance factor (R457), which is also called “blue brightness” or “ISO brightness”.
\n2. Analyze whether the sample material contains fluorescence brightener, and measure the fluorescence whiteness produced from fluorescence emission. i.e., whiteness degree.
\n3. Measure the whiteness stimulus value Y10 of samples, i.e., diffuse green reflectance factor Ry.
\n4. Measure the transparency, opacity, light scattering coefficient and light absorption coefficient of samples.
\n5. Measure the ink absorbency of paper and board.<\/p>\n
