Application
Tips: What is the maintenance requirement for the sodium sensor?
The sodium sensor requires minimal maintenance, making it a cost-effective solution for long-term water quality monitoring. To ensure reliable performance, it’s important to rinse the sensor with distilled water after use to remove any contaminants or residues that could affect the sensor’s readings. Regular calibration is also recommended to maintain accuracy, especially if the sensor is used in environments with fluctuating water chemistry. For long-term storage, the sensor should be kept in a dry environment or immersed in a standard electrolyte solution to prevent drying out or damage to the electrode.
