2. Colorimetry - Wikipedia

   en.wikipedia.org/wiki/Colorimetry

   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.

3. Colorimeter (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Colorimeter_(chemistry)

   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 to the absorbance.

4. Colorimetry (chemical method) - Wikipedia

   en.wikipedia.org/wiki/Colorimetry_(chemical_method)

   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.

5. Colorimetric analysis - Wikipedia

   en.wikipedia.org/wiki/Colorimetric_analysis

   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.

6. CIE 1931 color space - Wikipedia

   en.wikipedia.org/wiki/CIE_1931_color_space

   These color spaces are fundamental tools for measuring color for industry, including inks, dyes, and paints, illumination, color imaging, etc. The CIE color spaces contributed to the development of color television, the creation of instruments for maintaining consistent color in manufacturing processes, and other methods of color management.

7. Tintometer - Wikipedia

   en.wikipedia.org/wiki/Tintometer

   The Tintometer Limited was founded in 1896 [1] by Joseph Williams Lovibond, the son of a prominent brewery owner in Greenwich, London.J.W. Lovibond developed the world's first practical colorimeter as a means of ensuring the high quality of his beer.
