The Sea-Bird Scientific SeapHOx™ V2 system is comprised of the SeaFET™ V2 Ocean pH sensor and the SBE 37-SMP-ODO MicroCAT CTD+DO sensor. This system allows for collection and combination of pH data and critical oceanographic/biological measurements of temperature, salinity, and oxygen. The integrated package also enables the SeaFET™ V2 to take advantage of the MicroCAT’s pumped flow path and anti-fouling technology, extending deployment durations.
- The SeapHOx™ V2 is intended for moored applications of up to 50 m in depth
- The Deep SeapHOx™ V2 (bottom right) is intended for moored applications of up to 2000 m deep
Sea-Bird Scientific’s Deep SeaFET™, an ISFET-based pH sensor, demonstrates that the technology has reached the stability and robustness necessary for a transformation in the quality of in-situ pH measurements. The Deep SeaFET™ extends accurate pH measurements to two applications where depth, drift, and environmental constraints previously limited the availability of quality data:
- Autonomous profiling floats, which can perform hundreds of profiles in the ocean from depths of 1 to 2 km
- Deep, long-term moorings
The HydroCAT-EP uses a field-serviceable and replaceable glasselectrode sensor to measure pH to an initial accuracy of ± 0.1 pH. Specifically designed for long-term deployments in remote, biologically rich environments, it comes equipped with multiple anti-fouling systems. Factory calibration and streamlined reference checks enable users to generate scientifically defensible data with minimal time and cost required for field maintenance. Most sensors, including pH, are protected within the unique internal flow path by EPA approved anti-foulant devices. An integral pump minimizes the sensors' exposure to environmental waters, significantly reducing the impact of bio-fouling on sensor performance and drift. A copper faceplate and wiper protect the combination chlorophyll and turbidity sensor. The HydroCAT-EP measures:
