Explaining the ISFET pH Sensor

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...

Inductive Modem SeaFET/SeapHOx V2

Inductive Modem SeaFET/SeapHOx V2

April 2019 Newsletter Sea-Bird Scientific’s line of ISFET pH sensors only communicate via RS-232. However, savvy integrators can utilize the SBE 44 Underwater Inductive Modem as the link between the SeaFET/SeapHOx and an existing inductive modem mooring, providing...

Q&A: High Residuals in pH Data

Q&A: High Residuals in pH Data

March 2019 Newsletter The data shown above come from a SeapHOx V2 (red) and Deep SeapHOx V2 (blue) deployed next to one another in a dynamic estuarine environment. Regular pH validation samples were collected throughout the time-series. According to the 0.05 pH...

Q&A: What is Causing This “Feature” in pH?

Q&A: What is Causing This “Feature” in pH?

The data above originate from a SeaFET pH sensor connected to a flow-through system that should provide stable, consistent data. As you can see, the Internal pH value experiences a dramatic drop in pH and a subsequent increase in noise midway through data collection....

Reliably Measuring pH in the Ocean

Reliably Measuring pH in the Ocean

Although it’s barely the size of a breath mint, the Ag/AgCl reference allows the Deep SeapHOx V2 to dive deeper than any other pH sensor. Learn how a solid-state reference electrode allows the SeaFET V2, SeapHOx V2, and Deep SeapHOx V2 retain accuracy across a much...

pH Sensor Flowchart

pH Sensor Flowchart

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...

Video: Comparing the SeaFET V1 and SeaFET V2 Interface

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?

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

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

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...
