Online Water Quality

Online water quality refers to the continuous measurement of parameters such as pH, turbidity, and dissolved oxygen in water bodies through real-time sensor monitoring. It utilizes electrochemical or optical principles to convert physicochemical signals into data, which is applied in scenarios like industrial wastewater treatment and river ecological monitoring.
Selection
When selecting online water quality equipment, it is essential to consider the measurement parameters matching on-site requirements, sensor materials being compatible with water corrosiveness, the protection rating meeting the installation environment, data interfaces being compatible with existing systems, and regular calibration and maintenance to ensure data reliability.
