Dissolved Oxygen Technique
• The user may disable the automated process by selecting the setting
rather than .
• DO Manual Salinity Correction Factor Setting adjusts the dissolved oxygen
concentration in mg/L based on the samples salinity . Use the following table
to select an appropriate salinity factor . A typical value for Sea Water is 35,
but does vary considerably based on location .
