RBRcoda³ T.ODO

The RBRlegato³ can integrate the RBRcoda³ T.ODO sensors. The measurement principle of optical dissolved oxygen sensors is based on the luminescence quenching by oxygen.

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

Store the sensor in the dedicated storage cap, included with the instrument. Rehydrate for five days before deployment. See RBRcoda³ T.ODO care and maintenance for more information.
