Servicing the measuring cell
Since the continuous introduction of hot reaction gases during operation causes
electrolyte components to evaporate, it is recommended to change the electrolyte
solution once per day:
1.
Remove the used electrolyte.
2.
Rinse the measuring cell and the magnetic stirring rod with distilled water and
with ethanol.
3.
Then, carefully wipe out the measuring cell and wipe the magnetic stirring rod with
cellulose to remove any silver chloride deposits.
4.
Fill the measuring cell with fresh electrolyte:
Measuring cell "sensitive":
15 to 20 ml
Measuring cell "high concentration":
approx. 120 ml
Also observe the following notes:
If the system is decommissioned for several days, clean the measuring cell and
store it dry.
