PROBLEM TO BE SOLVED: To provide a residual chlorine meter whose pressure-resistant property is excellent and in which a pair of electrodes can be cleaned easily and to provide a liquid sterilization apparatus which uses the residual chlorine meter, in which it is not required to drain sample water and whose economical efficiency is excellent. SOLUTION: A measuring means 1 which measures the concentration of residual chlorine by using electrodes and a cleaning means which cleans the electrodes by using respective beads 2 are provided at a residual chlorine analyzer. The measuring means 1 is constituted in such a way that a pair of electrodes are provided, that a covering part which wraps the pair of electrodes internally is provided, that the beads 2 are arranged around the measuring means 1 and that the beads 2 flow by the flow of a liquid as an object to be measured. |
