RBRcoda T.ODO

The RBRlegato⁴ can integrate the RBRcoda T.ODO sensors, shown in Fig. 3. The measurement principle of optical dissolved oxygen sensors is based on the luminescence quenching by oxygen.

Store the sensor in the dedicated storage cap, included with the instrument. Rehydrate for five days before deployment. See RBRcoda T.ODO care and maintenance for more information.

Optical dissolved oxygen measurements require pressure correction for highest accuracy. When installed on an instrument with a pressure sensor, this correction is done automatically.
