5.2- Checking and maintenance of the Redox probe (OPTIONAL)
Select Menu, and Man. Chl.
Adjust the chlorine to 0%. Go back to the display screen. Rinse the probe carefully in clean water.
Insert the probe into a 465mV standard solution and stir gently. Observe the voltage on the label, which
corresponds to the ambient temperature at that time. Wait for the reading of the ORP value displayed on
the screen to stabilize.
Check that the value does not differ by more than about 10 mV of the value indicated on the label. If the
value is incorrect, it can be attempted to regenerate the probe by cleaning it. In any event, annual
cleaning is always advisable.
Stir the probe in a glass of water, in which a spoonful of dishwashing detergent has been mixed. Rinse
well in clean water.
Mix a commercial brand of hydrochloric acid at 23% in a glass, with four times its volume of water.
Leave the probe in the solution for a few minutes, stirring from time to time.
Thoroughly clean the probe in pure, preferably distilled water. Shake the probe to remove the water.
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.
5.3- 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 cm3 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.
5.4- Checking and maintenance of the Amperometric probe (PRO/2 kit)
Please, read carefully the 3.5.2 section of this manual.
