This invention, through the configuration of a solenoid valve, a cleaning agent inlet, a potassium chloride solution inlet, a pure water inlet, and nozzles, allows the pH sensor to be immersed in a special cleaning solution for pH electrodes, such as isopropanol or ethanol, via the cleaning agent inlet. This immerses the pH sensor, causing surface contaminants to detach. The solenoid valve then discharges the contaminated cleaning agent, while the pure water inlet, in conjunction with the nozzles, sprays pure water onto the pH sensor to remove water-soluble contaminants and residual cleaning agent. The three sets of nozzles, facing upwards, horizontally, and downwards respectively, are arranged in a circular array to ensure even rinsing of the pH sensor. This provides a good rinsing effect, and the contaminated pure water is discharged through the solenoid valve after rinsing. After rinsing, the solenoid valve is closed, and potassium chloride solution is then introduced into the treatment tank via the potassium chloride solution inlet for short-term immersion and preservation of the pH sensor, preventing damage. This effectively removes surface contaminants from the pH sensor and facilitates preservation, thereby extending the sensor's lifespan. Attached Figure Description
