Maintenance and Care Guidelines

Properly Clean Electrode Surfaces: After prolonged online operation, water quality sensors may develop scale or biofilm deposits on electrode surfaces, impairing measurement sensitivity. Regularly rinse electrodes gently with deionized water. For stubborn deposits, use designated diluted standard solutions for treatment. Avoid scraping the membrane surface with hard objects to prevent damage to the sensing layer.

Proper Storage and Soaking: For short-term deactivation, store potassium sensors in potassium ion standard solutions of appropriate concentration to maintain electrode activity. For long-term storage, dry preservation is recommended with dust protection to prevent performance degradation from prolonged air exposure.

Regular Calibration for Accuracy: To ensure long-term measurement stability, perform periodic calibration based on usage frequency. Particularly in environments with significant water quality fluctuations, closely monitor slope and repeatability changes, promptly correcting deviations.

Consider Operating Conditions and Installation Environment: During use, control pH range and temperature conditions. Avoid operation under overpressure or in environments with strong interfering ions. Regularly inspect cable and interface seals to ensure the sensor operates reliably and safely under stable conditions over extended periods.
