Precision
measurements
Recommendation: In order to carry out precision measurements, leave
the sensor to polarize for a longer period of time, e.g. overnight, and
recalibrate it the following day.
Note
In the following cases, you must refill the sensor once more:
 if there are large air bubbles
 if there are air bubbles on the gold working electrode
 for measurements at high water pressure, even if small air bubbles
are present. Otherwise, the membrane and, as a result, the
measuring characteristics could change.
 if the sensor cannot be calibrated.
