Unless it is used the electrode is to be stored in the protective flask filled with water or directly in a vessel filled
with dechlorinated water.
Residues of bacteria, fungi or algae must be removed prior to measuring using a soft paper towel.
If a calibration can no longer be carried out or if the membrane is damaged the electrode needs maintenance.
In the course of the time air bubbles may accumulated underneath the membrane. As long as they are small and
do not affect the silver cathode the measurements will not be influenced. If, however, there is a large ring of air
bubbles underneath the membrane covering the silver cathode, the electrode needs maintenance.
11.3 Electrode maintenance
Prepare liquid absorbing paper towel.
Remove membrane head and wipe off electrolyte solution with paper cloth.
Do not touch electrolyte. If your skin has come into contact with electrolyte, rinse thoroughly with clear water.
Clean silver cathode using sand paper (grain size 240). Do not shine silver cathode as its surface needs to be
rough so that the electrolyte can be dispersed evenly. Remove any dust from grinding.
If necessary, take out replenishing screw and top up with electrolyte till it is spilling out (e.g. using a disposable
syringe). Put back replenishing screw. (Normally not necessary).
Put new membrane head on the paper towel and fill up with electrolyte making sure there are no air bubbles.
Put electrode into head vertically from above till the thread catches. Then take up head with paper towel and
screw onto electrode from underneath. Electrolyte will be displaced from the membrane head, flowing over.
Mop up excess electrolyte using paper towel.
Turn electrode around and check for air bubbles. If there are no air bubbles or only tiny ones the maintenance
has been completed. If there are large air bubbles the process has to be repeated.
If O-ring has been damaged, it has to be replaced.
Prior to its being calibrated again the electrode needs to be lying on a table for at least 3 hours.
If electrode can no longer be calibrated although it has been properly maintained, the electrode
needs to be returned to manufacturer for check-up and may have to be replaced.
11.4 How to Operate
Store the oxygen electrode always in water
, either in the protective flask or directly in a vessel filled with
dechlorinated water. For storage in the protective flask first push the cap on the electrode second the o-ring and
thereafter put the electrode in the flask and screw the cap down the flask.
If the diaphragm has dried up the electrode must be soaked in water for approx. 2 h prior to measuring start-up.
Then a calibration can be carried out without any problems.
The electrode is only suitable for the devices OXY3610MP. Unsuitable devices may lead to the destruction of the
measuring device and the oxygen electrode!
For measuring remove the protective flask of the electrode.
The electrode measurement is sensitive against shocks!
By stirring of the electrode in the measured liquid be careful that the electrode does not hit the con-
tainer. A vibration of the electrode has an effect to the measured value.
