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 18 6 | Bases for measurement DO40-5 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.
