Care and Maintenance of Dissolved Oxygen Electrodes
The desktop dissolved oxygen meter ensures the stability and accuracy at (ultra) low concentrations, and has greatly improved in terms of measurement performance and use environment. The dissolved oxygen meter is mainly used for continuous monitoring of the dissolved oxygen value in chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water solutions.
Care and maintenance of dissolved oxygen electrodes:
1. The electrodes of the dissolved oxygen meter should be cleaned once every 1 to 2 weeks. If there are pollutants on the diaphragm, it will cause measurement errors. Care should be taken when cleaning, taking care not to damage the diaphragm. Rinse the electrode of the dissolved oxygen meter in clean water. If the dirt cannot be washed off, carefully scrub it with a soft cloth or cotton cloth.
2. The zero point and span should be re-calibrated in February to March.
3. The regeneration of the electrode of the dissolved oxygen meter is carried out about once a year. When the measurement range cannot be adjusted, the dissolved oxygen electrode needs to be regenerated. Electrode regeneration includes replacing the internal electrolyte, replacing the diaphragm, and cleaning the silver electrode. If the silver electrode is observed to be oxidized, it can be polished with fine sandpaper.
4. If the dissolved oxygen electrode leaks during use, the electrolyte must be replaced.
