HydroCAT-EP
Measures conductivity, temperature, depth, dissolved oxygen, pH, turbidity, and chlorophyll. It is ideally suited for extended deployments in remote, biologically rich environments, for depths to 350m. Specifically designed for long-term deployments in remote, biologically rich environments, it comes equipped with multiple anti-fouling systems.
