High accuracy
RBRcoda T.ODO: temperature and optical dissolved oxygen
The RBRcodaย T.ODO is an optode with exceptional performance. With a standard accuracy of 8ยตM 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 asโ|โslow (30s), standard (8s), and |โfast (1s) variants.ย The |โslow (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
