Dissolved Oxygen, mg/L
Sensor Type Calculated from % air saturation, tem-
perature, and salinity
Range 0 to 20 mg./L
Accuracy ± 0.2 mg./L
Resolution 0.01 mg./L
Conductivity*
Sensor Type Four-Electrode Cell

*Specific conductance (conductivity corrected to 25° C),
resistivity, and total dissolved solids measurements are
also provided. These values are automatically calcu-
lated from conductivity according to algorithms found
in Standard Methods for the Examination of Water and
Wastewater (ed. 1989).
