There are plenty of pH sensors on the market, with some recent additions showcasing novel technology and design. Among Sea-Bird Scientific’s holdings, we offer 7 different pH sensor models divided amongst 2 different technologies: ISFET and glass-electrode sensors. To...
ISFET pH
Video: Comparing the SeaFET V1 and SeaFET V2 Interface
Back in May 2018, Sea-Bird Scientific upgraded the SeaFET™ pH sensor to the “SeaFET™ V2”, improving upon the performance of the original SeaFET™ while retaining the same underlying ISFET sensor technology. The SeaFET™ V2 improves upon the original SeaFET’s...
Q&A: Two pH Sensors – what is causing this difference?
January 2019 Newsletter The data shown above originate from two different pH sensors deployed in the same well-mixed test bath. Both sensors were cleaned, tested, and calibrated before deployment, and were given 24 hours to equilibrate before recording data. So why...
Prototype pH Sensors: Eyes on an Experimental Kelp Farm
December 2018 Newsletter Spanning January to July 2018, two alpha SeapHOx V2s (serial numbers 001 and 002) tracked changes in pH at an experimental kelp farm funded by the Paul Allen Foundation. The purpose of the experiment was twofold: field-test the upgraded...
Basic Maintenance videos for the SeaFET V2
Upgrading to a SeaFET V2 from the original SeaFET is completely internal—aside from the most inaccessible hardware within the instrument, the V2 uses the same housing, sensors, and batteries as the V1. Therefore, the basic maintenance procedures for the V1 and V2 are...
Q&A: What is Causing the Difference between Internal and External pH?
The figure above originates from a single Shallow SeaFET V2 pH sensor, which produces two pH values (Internal pH and External pH) from two separate reference sensors. The black X’s indicate pH validation samples. While environmental conditions affect each the...
