HunterLab ColorFlex coffee spectrophotometer

The HunterLab ColorFlex coffee spectrophotometer measures the colour of ground-roasted coffee beans and provides the roaster with information on the colour and quality of green beens, ensuring a high-quality end product. 

Lacking universal grading standards, specialty coffee roasters often perform their own quality assessments, relying on time-consuming manual inspection. The ColorFlex device offers rapid and non-destructive colour assessment, removing the need for sorting and associated visual inspection imprecision. The spectrophotometer measures colour to facilitate more precise sorting and to enhance consistency.

Quality assessment of green coffee beans commences with visual inspection, which is subjective. The same visually inspected samples can be measured by the ColorFlex coffee spectrophotometer to provide numerically objective results. These results can be stored and used to establish standards, tolerances, comparison of batch to standard and variations batch to batch, for each species and geographical origin of the beans and their blends.
