While powders, grains and pastes, such as flour, sugar and cocoa, are largely dissimilar in their chemical and structural properties, they often share the common attribute of being opaque in nature and therefore benefit from similar color measurement techniques and instrumentation.
As with all opaque samples, best practices for color measurement dictate the use of directional 45°/0° reflectance geometry.
HunterLab offers several 'best in class' instruments designed specifically for color measurement of opaque samples. While many of HunterLab's spectrophotometers are versatile enough to accommodate most applications of color measurement, based on 60+ years of experience and a thorough understanding of our customers' needs and product use, these particular instruments are most suited for this industries application.
If you are unsure which instrument type is right for your samples, please call or email HunterLab technical support and we will be happy to assist you in making the proper instrument selection.
