More or less oxygen is dissolved in practically every liquid. Every liquid absorbs as much oxygen until the oxygen partial pressure in the liquid and the air or gas phase in contact with it is in equilibrium. The oxygen concentration determines, for example, the living conditions in bodies of water or degradation processes in wastewater treatment. In the past, oxygen - i.e. the oxygen concentration - was measured by titration according to WINKLER. Today, electrochemical and optical measurement are the methods recognized by the various standards. Here you will find our electrochemical meters for measuring dissolved oxygen - filter the measuring devices by selecting the term in the left-hand column.
