RH-48B Brightness Meter

Introduction:

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.

Standards:

GB 7973、GB 7974、ISO 2470、GB 8940.2、GB1840、GB13025.2、ISO2471、GB1033-89、GB 1543-88、GB T/5950、GB 2913、GB/ T24999

Technical Parameters:

Product Features:

1. Long service life
Light automatically open and close, greatly improve the normal service life.
2. Good repeatability and stability
Double light path compensation circuit, Strong anti-jamming, the results are accurate and stable.
3. Multi-function
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.
4. Easy to metrology, calibration
Equipped with standard whiteboard, facilitate users and calibration. Very easy to traceability and calibration.

Function:

1. Measure the diffuse blue reflectance factor (R457), which is also called “blue brightness” or “ISO brightness”.
2. Analyze whether the sample material contains fluorescence brightener, and measure the fluorescence whiteness produced from fluorescence emission. i.e., whiteness degree.
3. Measure the whiteness stimulus value Y10 of samples, i.e., diffuse green reflectance factor Ry.
4. Measure the transparency, opacity, light scattering coefficient and light absorption coefficient of samples.
5. Measure the ink absorbency of paper and board.
