Welcome and Thank You for Visiting Poseidon Flow Technologies

We are working on a few improvements to make our website even better. Product customizers are just a few of the improvements coming soon.

The Salinity Pen Plus+ (SP+) is a water resistant, portable, easy to use instrument that uses electrical conductivity to determine the Salinity/Specific Gravity of natural and/or artificial seawater. The unit rapidly displays Salinity (ppt), Specific Gravity (SG) and Temperature (Celsius/Fahrenheit), on an easy to read LCD screen. The SP+ can be easily calibrated in seconds using the included Salinity Standard Solution (30ppt).
