Salinity is a measure of the concentration of total dissolved salts in a body of water.

Salinity is ecologically important in that it influences the type of organism that can live in the water. The optimal concentration of salinity varies from species to species. It is crucial to the health of a system that this parameter is monitored.

Applications are found in an variety of fields from water in fish farming and aquariums as well as food processing and cheese production.

Salinity is expressed in g/kg or ppt (parts per thousand), as well as Practical Salinity Units (psu).
