The pH is a quantity (without units) measuring the acidity (0 to 7) or alkalinity (7 to 14) of the basin.
The pH is the concentration of hydrogen ions. For a swimming pool, the ideal pH generally
recommended is close to 7.3 (to be confirmed with your pool owner depending on your
installation).
Tip
The accuracy of the pH measurement is related to the regular maintenance of the pH
probe. It is advisable to check it regularly for any contamination (see Cleaning the pH or
RedOx probe [
