量モニター。 Chlorine and p in the sample water containing ammonia nitrogen
a chlorine addition section that adds an H adjustment reagent; a residual chlorine concentration measurement section that is connected to the chlorine addition section and measures the residual chlorine concentration in the test water sent from the chlorination section using a reagent containing bromide ions; A subtraction circuit connected to the residual chlorine concentration measuring section is provided, and the chlorine addition section adds an excess of chlorine of a known concentration and a pH adjustment reagent to the sample water, and maintains the pH at 7.5 or higher for a predetermined period of time. After that, this test water is introduced into the residual chlorine concentration measuring section to measure the residual chlorine concentration in the test water, and the value obtained by subtracting the above residual chlorine concentration from the chlorine concentration added to the test water by the above subtraction circuit is calculated as the chlorine demand. A chlorine demand monitor characterized by displaying the amount as a quantity.
