5 | Bases for measurement Dissolved oxygen measuring device 5 Bases for measurement 5.1 Oxygen sensor 5.1.1 Explanation The oxygen sensor is an active sensor. It consists of a platinum cathode, a lead anode and potassium hydroxide (KOH) as an electrolyte. If oxygen is present, it is reduced on the platinum cathode and the sensor delivers a signal.
Dissolved oxygen measuring device Bases for measurement | 5 5.1.2 Design Refill opening Shaft Membrane head Platinum electrode Storage bottle Platinum electrode If oxygen is present, it is reduced on the platinum electrode and the sensor delivers a signal. Soiling on the platinum electrode or between the membrane and electrode can influence the measurement.
5 | Bases for measurement Dissolved oxygen measuring device – Mechanical stress of the sensor membrane – Storage in dry air – Continuous use in elevated carbon dioxide concentrations 5.1.4 Operating position The oxygen sensor should be arranged vertically upwards with the connecting cable. A slight angle of inclination does not impair the measurement.
Dissolved oxygen measuring device Bases for measurement | 5 ter; the value is 0. A salinity of approx. 35 PSU is normal for sea water. The salinity correction is adjusted to aqueous media having a chemical composition corresponding to sea water. The International Oceanographic Tables (IOT) are used as a basis for the correction.
