9 Offset settings for different applications
The Offset setting is supposed to correct measuring deviations caused by different flow speed (v) around the elec-
trode:
For activated sludge basins and at flow speeds > 1m/s an offset
setting of ca –0.6 should be entered.
In between 0.3 and 1m/s the offset can be read from the dia-
gram. 0.3m/s correspond to the speed that is achieved by stir-
ring by hand.
Flow speeds below 0.3 m/s are not sufficient to get a correct and
reproducible measuring.
Für Belebtschlammbecken und bei Anströmungen > 1m/s sollte
ein Offset von ca. –0,6 eingegeben werden.
Zwischen 0,3 und 1m/s kann der Wert aus dem Diagramm aus-
gelesen werden. 0,3m/s entsprechen in etwa der Anströmung,
die beim Rühren per Hand erreicht wird.
Strömungsgeschwindigkeiten <0,3 m/s sind zu gering, um eine
genaue Messung zu gewährleisten.

11 Oxygen electrode
11.1 Construction of the sensor GWO 3600
11.1.1 General
The oxygen electrode is an active electrode consisting of a silver cathode and a lead anode using potassium hydrox-
ide (KOH) as an electrolyte. In case of oxygen being present it will be reduced at the silver cathode and the electrode
produces electric current. In case of no oxygen being present not current will be produced. Both the silver cathode and
the lead anode will be used up during oxygen measuring. The electrode ages. We, therefore, recommend regular
maintenance of the electrode at monthly intervals (see 11.3 Electrode maintenance).
Attention when working with electrolyte!
The electrolyte is caustic! (strong base, KOH)
Avoid contact to skin, protect Your eyes.
Protective equipment is necessary!
Irritates the skin and the mucous membranes, caustic.
When contact with the eyes immediately clean with water at least for 15 minutes.
Consult a doctor!
The membrane is delicate –if damaged, caustic electrolyte gets lost and the sensor shows
wrong signal.
Make it a rule to always store the electrode in a humid environment.
- in the storage flask filled with water
- in another container filled with water
If electrode has not been used for some time, clean membrane with soft cloth and remove de-
posits, if any (algae, bacteria etc.).
