text: In a process for the production of sodium hypochlorite from a solution of caustic soda and a current of gaseous chlorine in a chlorinator having inlet and discharge conduits wherein the concentrations and amounts of the mixture of said sodium hypochlorite, caustic soda and gaseous chlorine vary with time and said amounts of caustic soda and gaseous chlorine are regulated to maintain a slight alkalinity to prevent decomposition of said sodium hypochlorite, said regulation being performed by measurements of the redox potential of said mixture, the improvement comprising measuring said redox potential in at least one of said chlorinator and said inlet and discharge conduits, converting said redox potential into an impulse corresponding to the rst derivative of said redox potential relative to time and regulating by said impulse the addition of at least one of said caustic soda and chlorine,
