CTD Profiler SD204
Multi-parameter CTD instrument measuring conductivity, salinity, temperature, depth and sound velocity.
Description
The SD204 measures, calculates and records sea water conductivity, salinity, temperature, depth, sound velocity and density. Data are recorded in physical units and transmitted via RS232; newer units have a built-in radio transceiver like the SD208.
Key features
- Conductivity range 0 to 70 mS/cm, accuracy +/- 0.02 mS/cm
- Salinity range 0 to 40 ppt
- Temperature range -2 to +40°C, accuracy +/- 0.01°C
- Depth to 6000 meters
- Optional dissolved oxygen, fluorescence and turbidity sensors with auto-range
Applications
Remote readout is possible through the CU801 communication unit or the APB5 buoy over LTE or satellite.
