Dissolved Oxygen Setup Menu Options
Table 10 describes the options available in the Dissolved Oxygen
Setup Menu.
Salinity Factor — This feature adjusts the displayed dissolved
oxygen concentration in mg/L based on the sample’s salinity.
When the
Sal
icon is displayed during the reading mode, a salinity
correction calculation is applied to the dissolved oxygen
concentration in mg/L. The dissolved oxygen concentration in
% saturation is the ratio of the displayed concentration in mg/L to
the equilibrium dissolved oxygen concentration for the sample’s
temperature and salinity plus ambient barometric pressure.
