SeaFET V2 Ocean pH Sensor

SeaFET V2 Ocean pH Sensor
The SeaFET™ V2 Ocean pH sensor is an ion selective field effect transistor (ISFET) type sensor for accurate long-term pH measurements in salt water.

SeaFET V2 Ocean pH Sensor

Sea-Bird Electronics

The SeaFET™ V2 is the next generation pH sensor, upgraded from the original SeaFET™. The sensing element is an ion sensitive field effect transistor (ISFET). This class of device has been used for pH sensing in industrial processes, food processing, clinical analysis and environmental monitoring. The advantages of the ISFET include robustness, stability and precision that make it suitable for ocean pH measurement at low pressure. The ISFET potential is measured against two separate reference electrodes: one bearing a liquid junction (internal reference) and a solid state reference electrode (external reference), providing the user with the ability to assess instrument performance and ultimately achieve a greater understanding of the state of acid/base equilibria in seawater.

The SeaFET™ Ocean pH sensor has been used extensively for:
-ocean acidification research
-coral reef research
-coastal marine biology
-environmental monitoring.

The SeaFET™ Ocean pH Sensor was developed by Dr. Kenneth Johnson of the Monterey Bay Aquarium Research Institute (MBARI) and Dr. Todd Martz of the Scripps Institution of Oceanography, University of California San Diego. We collaborated with MBARI and Scripps to make the instrument commercially available to the research community. SeaFET™ sensors have now been deployed in many locations, including Canada, USA, Italy, UK, Australia and China.

SeapHOx
The SeapHOx combines the Satlantic SeaFET pH sensor with the Sea-Bird Electronics SBE 37-SMP-ODO MicroCAT CTD+DO sensor. The SeapHOx allows for the integrated data collection of pH with the critical oceanographic and biological measurement of temperature, salinity, and oxygen. The integrated package also allows the SeaFETTM to take advantage of the SBE 37's pumped flow path and anti-fouling technology, extending deployment durations in some cases.
