Colorimeter instrument

A colorimeter is an instrument used to measure the absorbance or transmittance of light by a solution or a solid material, typically to determine the concentration of a substance in the solution or the purity of the material. It is widely used in analytical chemistry, biochemistry, environmental science, and other fields.Colorimeters measure the intensity of light of a specific wavelength that passes through a sample and compare it to the intensity of light that passes through a reference sample. The difference in light intensity is used to determine the concentration of a substance or the purity of a material.
