摘要： PROBLEM TO BE SOLVED: To provide a water quality testing device using beads type cleaning elements, and its cleaning method. SOLUTION: A cleaning method of a water quality testing device provided with a measuring tank and beads type cleaning elements therein is as follows. The measuring tank has a first end part, a second end part, and inner side surface. The diameter of the first end part is larger than that of the second end part, and whole of or a part of the inner side surface is tapered and the inner cross section of the inner side surface is circular in the measuring tank. A measuring electrode is formed with the measurement surface face to the measuring tank at the second end part side. Inflow water swirling flow is formed by supplying inspection water in the tangential direction of the inner cross section, and outflow water swirling flow whose diameter is smaller than that of the inflow water swirling flow is formed in the vicinity of the second end part side. The beads type cleaning elements are collected at the second end part side and are contacted with the measurement surface. COPYRIGHT: (C)2009,JPO&INPIT
