PURPOSE: To provide an ozone water concentration measuring device in which the more precise ozone concentration can be continuously detected with a simple structure of crude electrode type both in running water and still water with a short response time. CONSTITUTION: This device is formed of a detecting electrode 30 and a reference electrode 40 dipped a solution to be measured, and a measuring part 50 for measuring the electromotive force between the detecting electrode 30 and the reference electrode 40. Either one or the both of the detecting electrode 30 consisting of nickel-chromium alloy (Xi-Cr alloy) or nickel-chromium alloy having a slight palladium (Pd) added thereto and the reference electrode 40 consisting of silver (Ag) or silver chloride (Ag/AgCl) are linearly reciprocated in the direction never changing the space with the partner electrode by a driving device 20. |
