PASPORT Salinity Sensor - PS-2195



The PASPORT Salinity Sensor works with the 10X Salinity Sensor Probe to measure salinity, conductivity, and temperature.  The sensor determines salinity based on electrical conductivity.  The sensor has a built in calculation to compensate for the change in conductivity due to temperature change which is based on the Practical Salinity Scale (PSS).

Typical Applications

  • Explore the salinity of local water sources
  • Explore the interrelationship of salinity, temperature and conductivity
  • Measure the change in salinity of saltwater as the water evaporates.

How It Works

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



Sample Rate
  • 50 Hz (maximum)
Temperature compensation
  • ±0.5 ppt from 0 to 45 °C at 33 ppt
Cell constant
  • 10X

Measurement Ranges

  • 1,000 to 100,000 μS
  • 0 to 50 degrees C
  • 1 to 55 ppt ±1% (with calibration)
