Colorimeter: Principles, Parts, Types, and Uses • Microbe Online
A colorimeter is a laboratory equipment used to measure the absorbance of light of particular wavelengths in a specific solution. The different solutions absorb light of a different wavelength equal to the concentration of the solution when exposed to light. This is the basis of colorimetry or simply Beer-Lambert’s Law.
Colorimeter (chemistry) - Wikipedia
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 ab...

Colorimeter - an overview | ScienceDirect Topics
Colorimeters evaluate the reflected color of a specimen using three sensors that respond to red, green and blue. Colorimeters are useful in color measurement, but they cannot detect mesmerism. They should not be used for setting standards; they are the least accurate and least expensive of the three types.
