Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and a mechanism, for the evaluation of the concentration of residual halogens, in which the replacement of the residual halogens is not required earlier than that in conventional cases and in which it is not required to execute their regeneration treatment. SOLUTION: In an evaluation method for the concentration of residual halogens, a main flow passage 1 for a liquid to be evaluated and an auxiliary region 2 which communicates with the main flow passage 1 are formed. An electrode 3 for potential measurement is arranged and installed in the main flow passage 1. A reference electrode 5 is arranged and installed in the auxiliary region 2 in a position in which residual halogens in the liquid to be evaluated are decomposed. In the auxiliary region 2, the residual halogens in the liquid to be evaluated are decomposed by a residual-halogens decomposing substance. The concentration of the residual halogens is evaluated on the basis of the potential difference between the reference electrode 5 and the electrode 3 for potential measurement.
