Sea-Bird SBE- 43 Dissolved Oxygen Sensor

Okeanus by 

Product Description

The SBE 43 is an individually calibrated, high-accuracy oxygen sensor to assist in critical hypoxia and ocean stoichiometric oxygen chemistry research on a variety of profiling and moored platforms. Careful choices of materials, geometry, and sensor chemistry are combined with superior electronics and calibration methodology to yield significant gains in performance.


Features

  • Voltage or frequency output.
  • Fully and individually calibrated; calibration drift rates of less than 0.5% over 1000 hours of operation (on time).
  • For use in CTD pumped flow path, optimizing correlation with CTD measurements.
  • Oxygen measurement dramatically improved because of improved temperature response.
  • Signal resolution is increased by on-board temperature compensation.
  • Continuous polarization eliminates stabilization wait-time after power-up.
  • Hysteresis largely eliminated in upper ocean (1000 m) due to improved temperature response. Hysteresis at greater depths predicatable and correctable in post-processing.
  • No degradation of signal or calibration when used for profiling in hydrogen sulfide environments.
