A colorimeter or photometer is used to measure the absorbance and transmittance of light in a solution. It operates on Beer-Lambert’s law, which relates light absorption to solute concentration. Clinical laboratories use it for blood glucose, protein, and enzyme estimations. Portable versions are available for environmental monitoring, particularly water quality testing. By providing rapid quantitative data, colorimeters improve diagnostic accuracy. Their role in biochemistry and diagnostics makes them indispensable in both hospital and research laboratories.
