A colorimeter is a device used to measure the color of a liquid or solid sample. It is commonly used in the fields of chemistry, physics, and engineering to measure the intensity of a color and its components. The colorimeter works by measuring the amount of light that is absorbed or reflected by a sample. This is done by passing a beam of light through the sample and measuring the amount of light that is absorbed or reflected.
Colorimeters come in a variety of shapes and sizes and can range in price from a few hundred dollars to several thousand dollars. The most common type of colorimeter is the spectrophotometer, which uses a monochromatic light source to measure the intensity of a color. Other types of colorimeters include the tristimulus colorimeter, which measures the amount of light absorbed in three different wavelengths, and the colorimeter, which measures the amount of light absorbed in a single wavelength.
Manufacturers of colorimeters include Beckman Coulter, Thermo Fisher Scientific, and Agilent Technologies. These companies offer a range of colorimeters, from basic models to more advanced models with features such as automatic calibration and data storage.
