Two pH Sensors: What is causing this difference?

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 does each sensor appear to be offset from the other, and why does the sensor shown in green appear to have gaps in data?

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. Watch our new video to learn how the restructured RS-232 interface affects how you use the SeaFET™ V2.
