SeaFET and SeapHOx
Since 2009, we have built over 60 autonomous pH sensors, based on the design described by Martz et al. 2010, for 13 different researchers collaborating with our group. Over the course of this work and an evolving design, two sensors emerged: the "SeaFET" and "SeapHOx". Both packages are based on a modified Honeywell DuraFET® ISFET pH sensor and the SeapHOx contains additional integrated sensors for dissolved oxygen (AADI 3835) and salinity (SBE-37). Throughout 2010, Scripps and MBARI (where Martz built the first SeaFET while working as a postdoc in Ken Johnson's group) have transferred the SIO SeaFET design to Satlantic Inc. where the sensor is now commercially available.

How Do I get a sensor?
Satlantic Inc. has commercialized the SeaFET. SIO does not typically "sell" the Scripps SeaFET and SeapHOx. They are built for our research and for our collaborators. If you wish to form a collaboration, please contact us.

Firmware Files for controller Rev. E, Sep 2011
Both sensors use alkaline D-cells. If you need a replacement battery, contact us or have any local battery shop copy the configuration of your dead pack (this will probably save you money).
See the User Guide for more info on the pack layout, dimensions, voltage, lifetime expectancy, etc.
For collaborative projects we can provide sensor maintenance as needed. Also, most of the part numbers are listed in the User Guide if you need to replace the DuraFET, ISE, fittings, o-rings, etc.
