Labtech PHOTO ELECTRIC COLORIMETER
A Labtech photoelectric colorimeter is an instrument used for quantitative analysis by measuring the concentration of a colored substance in a solution. It works by passing a light of a specific wavelength through the sample and measuring the amount of light absorbed or transmitted using a photodetector, which is then correlated to the substance's concentration via the Beer-Lambert law. These colorimeters are versatile, used in fields like biochemistry and environmental monitoring, and typically feature a rotating turret with multiple glass filters to cover a specific visible wavelength range (e.g., 400–700 nm).
