concentration value
Information on the solubility function:
The solubility of oxygen depends on the solvents, the dissolved
agents and the temperature. Oxygen partial pressure and
temperature are measured. The concentration is calculated according
to the solubility function for pure water (or seawater respectively)
stored in the instrument.
The solubility factor indicates the relative concentration difference to
pure water (or seawater).
Except for pure water the displayed concentration value is valid for
solutions of the same composition at calibration temperature only.
