PROBLEM TO BE SOLVED: To enhance cleaning efficiency of an electrode by introducing cleaning beads, along with measuring water, into the gap between the electrode of a residual chlorine meter and the side wall face having the same shape as the electrode. SOLUTION: In a bottomed tubular body having an electrode and containing measuring water, the bottom side wall face and the working electrode thereof are shaped to have protruding and recessed relation in the vertical direction while keeping a specified gap so that a creeping distance is attained. Cleaning beads are introduced, along with measuring water, in the upper lateral direction of the gap from the lower lateral direction thereof thus cleaning the working electrode. |
