摘要 |
The invention concerns a device for measuring concentration of chloroisocyanuric acid in equilibrium in an aqueous solution, comprising: first means (18, 10, 22, 24, 26, 28 30) to provide, relative concentration values of the various chloroisocyanuric derivatives; second means (14) for producing at least a first radiation beam (32) with wavelength ranging between 210 and 220 nanometers, capable of passing through said aqueous solution; third means (16) for measuring a first absorbance value of said first beam passing through said aqueous solution; and fourth means (18, 22, 24, 26, 28, 30) for determining the first absolute concentration values of the different chloroisocyanuric acid derivatives. |
