A colorimeter is a device used in colorimetry that measures the absorbance of particular wavelengths of light by a specific solution. [ 1 ] [ 2 ] It is commonly used to determine the concentration of a known solute in a given solution by the application of the Beer–Lambert law , which states that the concentration of a solute is proportional ...
A colorimeter is a device used to test the concentration of a solution by measuring its absorbance of a specific wavelength of light. To use this device, different solutions must be made, and a control (usually a mixture of distilled water and another solution) is first filled into a cuvette and placed inside a colorimeter to calibrate the machine.
Colorimetry is "the science and technology used to quantify and describe physically the human color perception". [1] It is similar to spectrophotometry, but is distinguished by its interest in reducing spectra to the physical correlates of color perception, most often the CIE 1931 XYZ color space tristimulus values and related quantities.
The equipment required is a colorimeter, some cuvettes and a suitable color reagent. The process may be automated, e.g. by the use of an AutoAnalyzer or by flow injection analysis. Recently, colorimetric analyses developed for colorimeters have been adapted for use with plate readers to speed up analysis and reduce the waste stream. [1]

A tristimulus colorimeter, colloquially shortened to colorimeter or colourimeter, is used in digital imaging to profile and calibrate output devices. It takes a limited number of wideband spectral energy readings along the visible spectrum by using filtered photodetectors ; e.g. silicon photodiodes .
