Description

The PASPORT Salinity Sensor works with the 10X Salinity Sensor Probe to measure the salinity, conductivity, and temperature of fresh to brackish water sources. The sensor determines salinity based on electrical conductivity. It also features a built-in calculation, based on the Practical Salinity Scale (PSS), that compensates for changes in conductivity caused by temperature changes.

The Salinity Sensor measures the electric current through a solution between the two platinum electrodes in the Salinity Sensor Probe. The current through the solution is due to the movement of ions, so the higher the concentration of ions in the solution, the higher its conductivity. A voltage (AC) is applied across the two electrodes in the tip of the probe and the measured current is proportional to the conductivity of the solution.

Examples of Water Salinity

Fresh water: <0.5 ppt

Brackish water: 0.5 to 30 ppt

Saline water: 30 to 50 ppt

Ocean Water: 35 ppt

Brine: >50 ppt
