Maintenance And Storage
The electrode should be cleaned regularly.
Be careful while disassembling and rinsing the chlorine membrane,
Do not wipe chlorine membrane on the electrode with filter paper or sandpaper.
If the membrane head is fouled and clogged, the electrolyte is dry, lack or is
contaminated. Stop using the membrane and its head should be removed and cleaned.
After cleaning the electrode, replace the membrane head, add electrolyte. After
long-term storage, it needs to be polarized and calibrated before use.
The cable connector must be kept clean, dry, free from moisture, water, acids, alkalis or
salts, etc.
If water supply is cut off or electrode is not used on site, the electrode should be taken
out, cleaned and covered with protective sleeve containing water for preservation.
If the electrode is not used and stored for a long time, remove the electrode, disconnect
the cable, drain the electrolyte, thoroughly clean the anode and the cathode with
deionized water at 30 °C-40 °C, dry it and put on the protective cover. Place it in a dry
place for storage.
