Salinity Sensor

Salinity Sensor product image

The Salinity Sensor precisely measures the total dissolved salt content of ocean or brackish water.


The Salinity Sensor easily and precisely measures the total dissolved salt content in an aqueous solution. Measure water with a wide variety of salinities, from brackish water to ocean water, and even hyper-saline environments. You can also study how salinity affects buoyancy or monitor salinity values in estuaries where fresh water mixes with ocean water.
