Claims

[Scope of utility model registration request]

(1) An electrode holder with an electrode for detecting water quality protruding from the tip that is immersed in the sample water, and a sample water inside the electrode holder, which is attached to the tip of the electrode holder so as to protrude from the electrode. an electrode cover 4 formed with a small-area introduction hole for introducing the electrode, a cleaning element disposed opposite to the electrode for removing minute deposits attached to the electrode, and a space in which the cleaning element and the electrode are arranged. An immersion type water quality measuring device, characterized in that it is equipped with a purge pipe, one end of which is open, the other end of which is branched, one of which is open to the atmosphere through a valve, and the other of which is connected to a pressurized air source. .

(2) The electrode is for pH detection, and the other end of the purge tube is the third
This branch pipe is connected to a pressurized fresh water source via a valve, and the pH is measured with the inside of the electrode cover filled with fresh water via the purge pipe, and the measured pH value is The immersion type water quality measuring device according to claim 1, which is characterized in that a detector abnormality signal is output based on the difference between the pH value and the pH value of fresh water that has been verified.
