COLOUR METRES

Colorimeters are used to measure and quantify the colour of a sample. The colour is determined from the transmittance or reflectance of solids, liquids, powders and pastes, and compared to different colour scales, e.g., AOCS, ASTM, Lovibond, Gardner, CIELab, Hunter Lab, Platinum-Cobalt/Hazen/APHA, Saybolt, etc. Measuring this parameter helps guarantee the consistency and quality of colour in products and materials. Colorimeters are commonly used in quality control, food and beverages, pharmaceuticals, cosmetics, petroleum, paints and coatings.
