Recheck the value of the probe. A probe that gives an error lower than around 30 mV can
continue to be used provisionally while it is replaced.
Never leave the probe outside. If the probe has been dry for a time, it can be regenerated
with the hydrochloric acid solution.
6.3 Checking and maintenance of the pH probe
It is recommended to clean and check the probe at least once a year. Stir it in a glass of
water in which a spoonful of detergent has been dissolved. Then wash it under the tap and
leave it for a few hours in a glass of water in which 1 cm
3
of hydrochloric acid has been added.
Recalibrate the probe again.
If well maintained, a probe can last for two or three years.
The probe should never be left to dry. If it is kept outside the installation, the original cap
should be placed, or it should be submerged in a glass of water. If a probe has been left to
dry, it can be regenerated by leaving it for 12 hours in a glass of water, preferably adding a
few drops of hydrochloric acid.
