RBRcoda3 T.ODO: temperature and optical dissolved oxygen

The RBRcoda³ T.ODO is an optode with exceptional performance. With a standard accuracy of 8µM but a power consumption of only 36mJ/sample, it is without a peer in optical oxygen measurement tools. Rated to 6000m depths and trivial to integrate, it is one solution for all deployments. Available as | slow (30s), standard (8s), and | fast (1s) variants. The | slow (30s time constant) version has a protective layer to facilitate automated cleaning by a wiper to keep it biofouling free during long-term moored deployments. The temperature channel compensates the foil and also provides an independent temperature output.

  • High accuracy
  • Low power consumption
  • Long deployments
  • Optical stability
  • RS-232 output
  • Depth up to 6000m
