Handheld industrial dissolved oxygen analyzerThe daily maintenance mainly includes regular cleaning, calibration, and regeneration of electrodes.

(1) The electrode should be cleaned once every 1-2 weeks. If there are contaminants on the membrane, it can cause measurement errors. Be careful when cleaning and be careful not to damage the diaphragm. Rinse the electrode in clean water. If the dirt cannot be washed away, carefully wipe it with a soft cloth or cotton cloth.

(2) The zero point and range should be rechecked in February and March.

(3) The regeneration of electrodes takes about one year. When the measurement range cannot be adjusted, it is necessary to regenerate the dissolved oxygen electrode. Electrode regeneration includes replacing the internal electrolyte, replacing the membrane, and cleaning the silver electrode. If there is oxidation phenomenon observed on the silver electrode, it can be polished with fine sandpaper.

(4) If electrode leakage is found during use, the electrolyte must be replaced.
