How is Salinity measured using this sensor?

FAQ - Conductivity

1. What is the difference between Conductivity and Specific Conductance?
2. Q: How is Salinity measured using this sensor? A: Salinity is a value that is derived mathematically from the conductivity readings. Hydrolab instruments use an algorithm from the USGS Water Supply Paper 2311 titled "Specific Conductance: Theoretical Considerations and Application to Analytical Quality Control" as the default. Users also have the option to choose the algorithm described in section 2520B od "Standard Methods for the Examination of Water and Wastewater."
