Summary

  1. (1)

    The study deals with the electro-chemical measuring of oxygen contents in lakes and activated sludge basins according to the method ofTödt. The non recording short time test is used.

  2. (2)

    Exterior influences (conductivity, temperature, current, cathode surface) are discussed.

  3. (3)

    An oxygen sounder with good properties as regards mechanical strength and sensibility of the electrodes is described.

  4. (4)

    As further development, combined sounders called ‘Oxytester’ for measuring temperature and oxygen, respectively temperature, oxygen and conductivity were designed.

  5. (5)

    The disturbing influence of temperature on testing of oxygen is compensated electrically.

  6. (6)

    Tests with the oxytester in lake investigations reveal continuous profiles of oxygen, temperature and conductivity. In this way fine proportions of stratification can also be ascertained precisely.

  7. (7)

    The immediate diagrammatical representation of the tested values during the work on the lake gives precious indications for further testings.

  8. (8)

    Possibilities of measuring by sounders are illustrated by the test profiles from investigations made in some of the lakes in the Swiss Midland.
