Abstract

PURPOSE:To prevent unstable indication by separating a sulfuric acid generation tank for feeding a reagent liquid from an alkali generation tank for feeding a conductive liquid through a cation exchange membrane. CONSTITUTION:A voltage is applied to electrolytic electrodes 15 and 16 feeding a fixed amount of a reagent liquid having sodium sulfate dissolved to a sulfuric acid generation tank 10 at a reagent liquid inlet 9 while a conductive liquid is fed an alkali generation tank 11 through an inlet 21 at a ceaseless flow rate. With an aid of a cation exchange membrane 19 conductive electrically but non- water permeable, sulfuric acid is generated in the sulfuric acid generation tank 10 through an electrolysis between the reagent liquid and the conductive liquid, while sodium hydroxide is generated in the alkali generation tank 11. The sulfuric acid thus obtained is mixed with a sample water fed from a sample water piping 12 and dripped into a mixing tank from an outlet 13. They are reacted and the current of the electrolytic electrodes 15 and 16 is so adjusted to reach a specified value in pH. The current value corresponds to the alkalinity of the sample water.
