21. PROBES MAINTENANCE
STARTING
Before using the electrodes, check that there are no incrustations, dirt or crystallisation. In case electrodes had it, soak them in
cleaning solution for 2 minutes.
PROBES CLEANING AND MAINTENANCE
Subject measuring electrodes to ocular inspections (approximately once per month) and clean them if necessary.
To clean them, submerge only the outer part of the electrode (glass) into the cleaning solution for 2 minutes. It is essential that after
every cleaning, the electrodes are put in KCI 3 M conservation solution for 5 minutes.
Filter cleaning and maintenance once a week with pressure water.
STORAGE
ORP and pH probes must have the outer part (wet zone) into KCI 3M conservation solution. For this purpose, pour some KCI
trimolar solution into the protecting hood.
The sponge of the protecting hood must always be wet with this solution.
All electrodes are individually tested before delivery. Storage in dry condictions, 10ºC to 30ºC. In temperatures below -
15ºC the electrodes may fracture due to freezing of buffer and electrolyte.
: pH and Redox probes cannot be stored for an indefinite time. Therefore, it is not suitable to store them for
more than three months.
: Do not soak electrodes into distilled water because it would cause premature aging.
LIFE TIME
ORP And pH probes are put to a natural aging, even they are handled according to the ruled usage. Lifetime will be within half a
year and two years as a maximum time.
