    Multi 3510 IDS Glossary Glossary pH/ORP Asymmetry see zero point Electromotive force of The electromotive force U of the combination electrode is the measur- an electrode able electromotive force of an electrode in a solution. It equals the sum of all the galvanic voltages of the combination electrode. Its dependency on the pH results in the electrode function, which is char- acterized by the parameters, slope and zero point.
  • Page 102 Glossary Multi 3510 IDS Salinity The absolute salinity S of seawater corresponds to the relationship of the mass of dissolved salts to the mass of the solution (in g/kg). In practice, this dimension cannot be measured directly. Therefore, the practical salinity according to IOT is used for oceanographic monitor- ing.
