Sea-Bird Scientific HydroCAT-EP - Long-Term Deployment Water Quality Sonde

• Product type: Unattended
• Parameters measured: Temperature, Pressure, Dissolved Oxygen, Conductivity, pH, Turbidity and Chlorophyll
• Product highlights: Designed specifically for long-term deployments of up to three months
• Interface:SDI-12, RS232

• Low total cost of ownership: Annual calibrations, a five year warranty, and deployment durations of three months mean less cost to service and maintain over the life of the instrument.
• Data Reliability: With the exception of pH all sensors are factory calibrated in a temperature-controlled bath that operates at 2 -4 times the accuracy of the instrument
• Easy to service: The pH sensor is a smart sensor that can be hot swapped in the field minimizing the need for in field service and calibration.
