Claims

[Claims for Utility Model Registration] A microbial electrode consisting of a diaphragm-type oxygen electrode and a microbial membrane; A flow cell arranged with respect to the electrode, a liquid introduction path connected to the liquid inlet of this flow cell, a buffer supply section that continuously supplies a buffer solution to this liquid introduction path, an air supply section that supplies aeration air, and the above-mentioned The introduction path is provided with a liquid to be measured introduction part that selectively introduces any one of the cleaning liquid, the standard solution, and the test water, and the liquid to be measured connects the liquid introduction path and the cleaning liquid supply line. It consists of a selection flow path with a standard solution supply line and a test water supply line connected in a branched manner in the middle, and a pinch valve type solenoid valve attached to each line in front of these connections and joints. , and the branch-like joint portion is constituted by a transparent tube.・
