Sea-Bird Coastal HydroCAT

    • Robust: excellent anti-fouling capability – EPA approved anti-foulant device and pumped internal flow path for maximum biofouling protection
    • Accurate: each instrument is factory calibrated in a temperature-controlled bath that operates at 2-4 times the accuracy of the instrument.
    • Cost Effective: no in-field calibrations required, common deployment duration of three plus month, reducing field costs
