Abstract (en)
[origin: WO2011003923A1] The invention relates to a device for measuring at least one physico-chemical parameter of water, said device including a means for measuring the concentration of active chlorine in the form of hypochlorous acid HOCl in said water. According to the invention, said means for measuring the chlorine concentration in the form of hypochlorous acid HOCl includes first (21) and second (22) amperometric sensors for detecting chlorine in the form of hypochlorous acid HOCl, each outputting a signal, said two amperometric chlorine sensors (21, 22) having a single common reference electrode (25) and being connected to a double potentiostat, characterised in that said invention includes a means for simultaneously implementing said first (21) and second (22) amperometric sensors, and in that said invention includes a means for measuring a difference between the signals output by said two sensors (21, 22).
