Learn how to replace a Satlantic SeaFET Ocean pH Sensor.

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.  Satlantic has collaborated with MBARI and Scripps to make the instrument commercially available to the research community.

The sensing element of the SeaFET 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.
