clean cloth or water to clean it. For ion electrodes using PVC ion exchange membranes, it is usually
necessary to replace the membrane head (or depends on the use of the electrode) for half a year.

Procedures of Replacing Electrolyte
1. Unscrew the electrode cap of the ion electrode: pour out the remaining electrolyte in the electrode
body;
2. Use a pipette to put a small amount of electrolyte into the electrode body: (If the electrode is used
for a long time, it is suggested to put a small amount of deionized water in the electrode body first and
clean it according to procedure 3, and later add a small amount of electrolyte)
3. Slightly shake the electrode up and down to clean it. After cleaning, pour off the electrolyte.
4. Re-use the pipette to place the electrolyte into the electrode body until the electrolyte forms a
