The RBRduet³ T.ODO is a compact and rugged self-contained logger with many applications. The optical oxygen sensor provides high stability for very long deployments where accurate dissolved oxygen concentration and oxygen saturation measurements are critical. The marine thermistor provides the highest accuracy temperature measurement with 1s time constant. The |fast version has a 1s time constant for dissolved oxygen. The |slow version has a protective layer over the optical foil to remove fouling for long-term moored applications. 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.
