摘要
The present invention relates to a method for continuously measuring the concentration of trichloramine in the air of an enclosed space containing a pool of chlorinated water, comprising the following steps: a - measuring the concentration C1 of oxidising gases in the ambient air inside the space using at least a first electrolyte-based amperometric electrochemical sensor which is protected by a gas-permeable membrane and the fixed working potential of which is greater than 1.1 V; b - measuring the decrease in the concentration C2 of free chlorine in the pool of water, the decrease being averaged over a period of at least 4 hours, advantageously 12 hours, and converted into the unit of measurement of C1; c - obtaining the final concentration Cf of trichloramine in the ambient air inside the space by comparing the concentrations C1 and C2 and selecting the lower of these concentrations.
