ISFET pH sensors, like the SeaFET V2 and SeapHOx V2, receive a factory calibration, and don’t require regular field maintenance. Learn how we’ve adapted our calibration facility to account for conditions these instruments meet in the wild.

pH Training: Past and Present
October 2019 Newsletter On October 31st, Sea-Bird Scientific presented a hands on technical training at the OCEANS ’19 conference in Seattle, WA. If you could not attend, watch a recording of our live webinar, presented on July 18th 2019, outlining how our latest line...
Q&A: Unusual Test Bath Data – a Cautionary Tale
September 2019 Newsletter These data show a small but rather catastrophic deployment error. Shown above, pH and dissolved oxygen data before the highlighted area did not match bottle samples or nearby validation sensors, but data after the highlighted area accurately...
How many pH samples can you fit into a year?
How long can you really trust your sensor to sip energy from its batteries? Properly selecting the right sample interval must strike a balance between a high-resolution dataset and a complete time-series. After some quick calculations, we’ve found the optimal sample...
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
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
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?
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
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...
