The HydroCAT-EP V2 Multiparameter CTD: Precision Insights for Environmental Monitoring

Dive into the future of environmental monitoring with Sea-Bird Scientific's cutting-edge HydroCAT-EP V2 (HCEP-V2). This multiparameter CTD offers an impressive dynamic range, seamlessly transitioning from deep ocean environments to coastal waters, all while delivering high-resolution data and enhanced signal-to-noise ratios across every channel. We took the field-proven MicroCAT (SBE 37) and added a host of integrated sensors to the base CTD to provide users with a robust sampling platform in a compact, self-contained package.

The HydroCAT-EP V2 integrates seven field-proven sensors that are factory and/or field-calibrated (pH only) to provide optimal accuracy and long-term data stability. With optional optical dissolved oxygen, chlorophyll, turbidity, pH, and pressure sensors, the HydroCAT-EP V2 provides a solution for any ocean, coastal, or freshwater application. It has an integrated pump that operates each time the system takes the measurements, flushing the measured water and quickly moving new water into the flow path to achieve measurements at the highest accuracy.

The HydroCAT-EP V2 uses a field-serviceable and replaceable glass-electrode sensor to measure pH to an initial accuracy of ± 0.1 pH. Like many glass-electrode pH sensors, it is deployable in freshwater and marine environments and can be calibrated in the lab or field with standard, clear pH buffer solutions. Unattended, the HydroCAT-EP V2 can measure up to 3 months of high-quality pH data while retaining stability for at least 1 year for all other sensors. This timeline reduces overall field servicing costs and data gaps.

Your data is more than the sum of its parts. The interplay between physical and biogeochemical parameters tells a rich scientific story – a story that can only be uncovered by a diverse sensor array. Rising dissolved oxygen could be caused by many things, but a corresponding dip in pH and wave of fluorescence illuminates the algae growing beneath the surface. To find these nuances, you need the proper environmental monitoring tool.

The HydroCAT-EP V2 adds the following parameters to moorings:

• Temperature
• Conductivity
• Pressure (optional)
• pH (optional)
• Dissolved Oxygen (optional)
• Fluorescence (optional)
• Turbidity (optional)
