Web10 jun. 2024 · Example: Step one: Sample is measured to have 80% DO saturation, 0 ppt salinity, at 20ºC. Step two: Multiply .80 (which is the DO %) by 9.09 (value from oxygen solubility table at 0 salinity and 20ºC) = 7.27 mg/L. Result: 7.27 is the mg/L value that corresponds to an 80% DO Saturation reading of a sample with zero salinity at 20º C. Web8 sep. 2024 · Read the measurement.
