The tester adopts the ultraviolet ray absorption principle and is based on the Beer-Lambert law to inspect the ozone concentration without the use of chemicals.
7,8,9) The Beer-Lambert law is the mathematical principle used to describe light absorption and the properties of the material through which the light is traveling.
The Beer-Lambert law states that when light passes through a solution containing some concentration of dye, the amount of light absorbed by the dye solution is proportional to both the concentration of dye and the pathlength of the light with the solution.
