A colorimeter measures light absorbance to check solution concentration.
About Us
Colorimeters
A colorimeter is a scientific instrument designed to measure the absorbance or transmittance of specific wavelengths of light in a solution. Unlike a spectrophotometer, which can cover a broad spectrum, a colorimeter focuses on selected wavelengths, making it simple, reliable, and cost-effective. Today, various types are available, such as digital colorimeters, portable colorimeters, photo colorimeters, and digital photo colorimeter systems.

Working Principle of a Colorimeter
So, how does a colorimeter work? The device passes a beam of light through a sample solution. A colorimeter sensor detects how much light is absorbed, and this measurement is directly related to the concentration of the solution. This makes it a valuable tool in chemical analysis, biological studies, and industrial quality control.
