Biorays colorimeter is a device used to measure the intensity of colors or the concentration of a substance in a solution based on its color. It is widely used in various scientific fields, including chemistry, biochemistry, environmental science, and quality control. A colorimeter works by quantifying the amount of light absorbed or transmitted by a sample at a specific wavelength, which correlates with the color or concentration being measured.
