Introduction:dissolved oxygen meterMainly used for continuous monitoring of dissolved oxygen values in solutions such as chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.
　　
(1) Cleaning should be done once every 1-2 weeksdissolved oxygen meterIf there are contaminants on the electrode membrane, it can cause measurement errors. Be careful when cleaning and be careful not to damage the diaphragm. Rinse the dissolved oxygen meter 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 of the dissolved oxygen meter electrode should be rechecked from February to March.
　　
(3)dissolved oxygen meterThe 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 the electrode of the dissolved oxygen meter leaks during use, the electrolyte must be replaced.
　　
Referring to the above,dissolved oxygen meterThe use of purchased products is not only about using them correctly, but also about maintenance. Many customers have problems before using them. Most of them are caused by technicians accidentally touching the membrane head when taking out the electrode, breaking the thin film. This leads to excessive negotiations and turnover for repair between customers and suppliers. Therefore, being able to use products in a formal and careful manner can avoid many unnecessary troubles.
