RBRcoda³ - Model T.ODO -Optical Dissolved Oxygen Sensor
FromRBR Ltd.
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 version has a protective layer over the foil to allow it to be cleared of biofouling for long-term moored applications. The temperature channel compensates the foil and also provides an independent temperature output.
