HydroCAT-EP V2 Multiparameter CTD Sensor
Factory calibration and streamlined reference checks enable users to generate scientifically defensible data with minimal time and cost required for field maintenance. The HydroCAT-EP can be easily integrated with external data loggers and telemetry systems. Specifically designed for long-term deployments in remote, biologically rich environments, it comes equipped with multiple anti-fouling systems. 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 V2: Built for Tough Environments
The HydroCAT‑EP V2 delivers robust, long‑term CTD and biogeochemical measurements in biologically rich waters. With integrated anti‑fouling, modular pH, multi‑sensor flow‑path design, and year‑long stability, it reduces servicing while ensuring high‑quality coastal data.
Key Features
- Robust: EPA-approved anti-foulant device and pumped internal flow path for maximum bio-fouling protection. Superior electronics with low drift rate.
- Accurate: Each instrument is factory calibrated in a temperature-controlled bath that operates at 2-4x the accuracy of the instrument.
- Cost Effective: No in-field calibrations required. Common deployment duration of three months to one year, reducing field costs

Long-Term Water Quality Monitoring Deployments with the Sea-Bird HydroCAT-EP
Sea-Bird Scientific’s HydroCAT-EP was deployed for 3.5 months in Shilshole Bay, Puget Sound, Washington, to evaluate its long-term water quality monitoring capabilities under moderate to high biofouling conditions. The instrument demonstrated high accuracy and stability in measuring parameters like dissolved oxygen, temperature, conductivity, pH, turbidity, and chlorophyll, with minimal maintenance required.
