RBRcoda ODO | Dissolved Oxygen Sensor

The RBRcoda ODO is designed from the ground up to provide exceptional stability while reducing the power consumption typically seen in optodes. It consumes only 36mJ/sample, permitting massive increases in deployment autonomy. The standalone sensor has serial and analogue outputs, while the OEM variant is designed for flush-mounting in custom pressure vessels (gliders/ARGO floats/etc).

  • Power consumption an order of magnitude less than other optodes
  • Optical sensor provides long term stability
  • Accurate temperature channel compensates foil and also provides independent temperature output
