Explaining the ISFET pH Sensor
May 2019 Newsletter
ISFET-based pH sensors have been used to measure pH in industrial settings for years (do you know the pH of your last beer?). It’s the adaptation of this technology for measuring ocean pH that makes the SeaFET V2 and SeapHOx V2 novel tools for the scientific community. Watch Matthew, one of Sea-Bird Scientific’s Electrical Engineers, give a high-level explanation of the ISFET circuit and how it is ultimately able to measure pH in the ocean.
