colorimeter

Colorimeter is used in chemical sciences. In the scientific field, a color meter or colorimeter generally refers to a device that measures the absorption of specific wavelengths of light in a solution. [1] This device is usually known for determining the concentration of a solvent and using a certain solution using Beer-Lambert's law is able to measure the concentration of a solvent proportional to the absorption of light.

From the digital photometry technique or color analyzer with accessories with the ability to select automatic wavelength and using a smart microprocessor, the measurement of quantities such as chlorine, ammonia, copper, zinc bromine CO, etc. can be done easily.
