Temperature and Optical Dissolved Oxygen Made Easy

Introducing the RBRduet³ T.ODO – a compact and rugged self-contained logger for measuring high accuracy temperature and DO measurements.

The optical oxygen sensor provides high stability for very long deployments where accurate dissolved oxygen concentration and oxygen saturation measurements are critical. The |fast version has a 1s time constant for dissolved oxygen. The |slow version has a protective layer over the optical foil to allow wiping to remove fouling for long-term moored applications.


The marine thermistor provides the highest accuracy temperature measurement with 1s time constant.

The compact size and self-logging ability is versatile and enables DO measurements in a variety of applications including oceanographic moorings, fishery studies, benthic pods, and non-integrated attachments on AUVs, glides, and profiling floats.
