13.1.3 Activation
-
Remove the protective casing by pulling and twisting the entire assembly1.
-
Connect the electrode to the measurement box.
-
Dip the electrode in the water to be analysed.
Comment :
The sensor must be rinsed in deionised water between measurements. Failing this, use Volvic or
demineralised water.
13.1.4 Maintenance
-
After use, rinse the electrode in demineralised water.
-
Return the sensor to the protective casing after having checked that the casing contains several drops of
storage solution or if not available, KCL saturated solution.
Do not store the REDOX sensor in the protective casing filled with water (especially very clean
water) for long periods of time.
Although the reference solution may have a considerable amount of KCl salt content, it may be
depleted and used up prematurely if the salt is distributed in water with a low ionic strength.
If you have no suitable storage solution or saturated KCl solution (a few drops is sufficient in both
cases), you can simply moisten the inside of the protective casing before storage so as to maintain
an atmosphere conducive to hydration of the glass pH bulb.
13.1.5 Cleaning
-
Rinsing in demineralised water is normally quite adequate.
-
If the sensor is dirty, soak it in an Eh cleaning solution ( HCl) for one hour.
-
In the case of extreme poisoning (sulphur, etc.), gently rub the platinum ring with a scotch-brite light
duty scrub type sponge for example.
-
From time to time, grease the O-Ring seals on the delrin shaft with vaseline. The casing will slide easier
and storage water-tightness is improved.
13.2 Temperature sensor
