摘要：

<P>PROBLEM TO BE SOLVED: To provide a residual chlorine measuring instrument with a satisfactorily cleaned electrode. <P>SOLUTION: This residual chlorine measuring instrument is equipped with a measurement tank 1 with a measurement chamber 1a formed therein for measuring residual chlorine, an electrode unit 2 mounted on the measurement tank 1, beads 3 housed within the measurement tank 1 and used for cleaning the electrode unit 2, an outer tube body 4 for forming annular flow path 4a between itself and a peripheral surface of the measurement tank 1, and a piping unit 5 connected to the measurement tank 1 and to a lower side of the tube body 4. The beads 3 are carried on an upward stream of a measuring fluid to jet toward a detection surface 2a of the electrode unit 2, thereby cleaning the detection surface 2a. <P>COPYRIGHT: (C)2006,JPO&NCIPI
