21.2 Maintenance Of The Membrane
The membrane does not require replacement as long as it remains
intact. If punctured or suspected of leaking around the edges, it must be
replaced.
To replace the membrane, please see the separate instruction leaflet
supplied with the EDYSI sensor.
21.3 Probe Storage
The Oxygen probe should be kept moist when not in use to prevent the
thin film of electrolyte behind the membrane from drying out. To achieve
this, the probe can be stored with the tip in water.
If the membrane does dry out, gently pump the pressure compensating
diaphragm (approx half way up the probe). This will re-flush the gap
between the gold cathode and the membrane with fresh electrolyte. DO
NOT USE A SHARP OBJECT, AS THIS MAY RUPTURE THE
DIAPHRAGM.
For long term storage of several weeks or more…
1. Remove the membrane
2. Hold the sensor with the tip facing downwards and gently pump the
pressure compensating diaphragm until the sensor is empty.
3. Rinse the inside of the sensor tip with distilled water.
4. Fit a new membrane WITHOUT REPLACING THE ELECTROLYTE.
5. Remember to re-fill the sensor and fit a new membrane before its next
use.
