Powder objects such as coatings, inks, medicines, foods, etc., require special measurement methods due to their particular physical properties.
How to detect color difference when the measured object is powder?
When measuring powdery objects with a Spectrophotometer , the measured value will vary depending on the powder density and surface condition. In order to avoid large deviations, some special methods can be used, for example, a certain amount of powder can be taken, put into a container with a certain shape and size and keep the surface properties unchanged.
If the measured object is large in size, a Spectrophotometer with a large measuring aperture can be used, so that the measured surface can be more even and the repeatability of the data can be guaranteed.
