Feature of HD-A822-1 Brightness & Opacity Meter:
- HD-A822-1 Brightness & Opacity Meter is a precision instrument used to measure the brightness and opacity of paper, cardboard, and other sheet materials.
- The HD-A822-1 provides reliable data for evaluating paper whiteness, brightness, and coverage, helping manufacturers maintain consistent quality standards.
- Brightness & Opacity Meter is mainly used to measure the whiteness of paper, paperboard, chemical fiber, textile, plastic, grain, starch, salt, white cement, porcelain clay and talcum powder, etc.
- HD-A822-1 can also be used to measure the opacity and other optical performance of thin material.
- Measure the diffuse blue reflectance factor (R457), which is also called “blue brightness” or “ISO
- brightness”.
- Analyze whether the sample material contains fluorescence brightener, and measure the fluorescence
- brightness produced from fluorescence emission. I.e. brightness degree.
- Measure the brightness stimulus value Y10 of sample, i.e. diffuse green reflectance factor Ry.
- Measure the transparency, opacity, optical-absorption coefficient and light-scattering coefficient of
- samples.
