The Sea-Bird Scientific HydroCAT-EP is ideally suited for extended deployments
in remote, biologically rich environments. Factory calibrated, field proven sensors
ensure long term data stability. Depending on the application, the HydroCAT-EP can
collect high quality data for several months up to a year. Excellent bio-fouling protection for conductivity, temperature, optical dissolved
oxygen and pH is provided by EPA-approved anti-foulant devices, an integral pump,
and a unique internal flow path, which minimizes flow between samples and provides
stable measurements throughout a deployment. The combination chlorophyll and
turbidity sensor is protected by a copper face plate and wiper. All HydroCAT-EP sensors are built with careful choices of materials and geometry
combined with superior electronics and calibration methodology to optimize field
performance.
