Product Description

ASR-5635 Whiteness Meter is used to measure the blue light whiteness of the surface of the object, and the measurement result is displayed on the LCD. Applicable to textiles, printing and dyeing, chemical fiber, plastics, porcelain clay, talcum powder, white cement, paint, paint, ceramics, enamel, paper, pulp and other departments that need to measure the whiteness of products.

5635 meter is a special instrument for measuring the whiteness of objects. Widely used in whiteness measurement of paper and cardboard, textile printing and dyeing, paint coating, chemical building materials, plastic products, cement, calcium carbonate powder, ceramics, enamel, china clay, talcum powder, starch, flour, salt, detergent, cosmetics, etc.

The main function

1. Measure the ISO brightness (ISO Brightness, that is, R457 whiteness). For fluorescent whitening samples, the fluorescent whitening degree produced by the emission of fluorescent substances can also be measured. 

2. Determination of lightness stimulus value. 

3. Measure Opacity. 

4. Measure transparency. 

5. Determination of light scattering coefficient and absorption coefficient.

6. Determination of ink absorption value.

7. Measure the reflected optical density.

8. Determination of lead concentration
