6. Malfunctions
If you obtain an unstable reading, make sure there are no air bubbles in the glass electrode.
If there are bubbles in the electrode, remove them by shaking the electrode the same way
you would a medical thermometer. If the problem persists, change the electrolyte and if
necessary the probe head.
If you cannot calibrate the probe (it will not rise to 5.82%, blockage at 10%, etc.), gently
clean the tip of the electrode with an absorbant tissue soaked in alcohol, change the
electrolyte, and if necessary the probe head.
Note:
The calibration described above is a precise calibration. For qualitative work (variations in

precise calibration.
Attention: The electrode must be polarized (see Ch III).
In the event of a persistent blockage of the probe at 10%, remove the probe head and rinse
the electrode copiously with distilled water until a response is obtained.
7. Testing the probe
You can test the polarization of the probe by connecting it to a pH meter that reads in mV.
The value obtained should be between -180 and - 240 mV with the probe in the air.
8. Storage and care
The probe is stored in open air, with the probe
Place the probe with the head facing downwards and protect it from being jarred.
