Page 13: Bases For Measurement
DO-400 Bases for measurement | 6 6 Bases for measurement 6.1 Oxygen sensor 6.1.1 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. -

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. - Page 17 DO-400 Bases for measurement | 6 3. Fill the pipette with the KOH electrolyte and initially fill the membrane head to ¾ full. Rinse off the excess electrolyte. 4. Slowly fill the sensor via the fill opening. In the process, tilt the sensor from side to side and tap the shaft to force out air bubbles.
