HydroCAT

Depending on the application, the HydroCAT can collect high quality data for several months up to a year.

Excellent bio-fouling protection is provided by US EPA-approved anti-foulant devices, integral pump, and unique internal flow path, which minimizes flow between samples and provides stable measurements throughout a deployment.
Conductivity and temperature sensors are based on field proven Sea-Bird Electronics (SBE) CTD products. The aged and pressure- protected thermistor has a long history of exceptional stability and accuracy. The oxygen sensor was designed by SBE to meet the demand for a low maintenance and high accuracy sensor for use in applications such as hypoxia monitoring. All HydroCAT sensors are built with careful choices of materials and geometry combined with superior electronics and calibration methodology to optimize field performance.
Features
  • 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
