Whiteness and colorimeter
Application：
The whiteness and colorimeter is a detection instrument that measures the color, color difference and whiteness of objects based on the principle of light reflection. Used for paper, paperboard, pulp, ceramics; Powders such as cement, starch, calcium carbonate and talcum powder.
Product function:
- Measure the color and color difference reflected by the object
- Measure the brightness of D65 (blue light whiteness of R457)
- Determine the fluorescence brightening degree produced by the emission of fluorescent substances (the sample contains fluorescent brighteners)
- Determine CIE whiteness (Gantz whiteness W10 and color deviation value TW10)
- Determine the whiteness of ceramics, building materials and non-metallic mineral products
- Determine the Hunter system Lab and Hunter (Lab) whiteness
- Determine the yellowing degree and ink absorption value
- Determine the opacity, transparency, light scattering coefficient and light absorption coefficient of the sample
