Compact Optical Dissolved Oxygen Logger for Oceanographic Measurements

RBR is proud to release the new RBRduet³ T.ODO optical dissolved oxygen logger.

The RBRduet³ T.ODO is a compact and rugged self-contained logger for your many applications down to 6000m. The optical oxygen sensor provides high stability for very long deployments where accurate dissolved oxygen concentration and saturation measurements are critical. The marine thermistor provides the highest accuracy temperature measurement. The |fast version has a 1s time constant for dissolved oxygen measurements on profiling or moving platforms. The |slow version has a protective layer over the optical foil to allow it to be wiped of biofouling 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.

"Based on broad customer request for a compact logging optical dissolved oxygen sensor, we are very pleased to release the RBRduet³ T.ODO compact logger," said Eric Siegel, Sales Director. "This product is building on the past two years of customer success in using hundreds of the RBR-developed T.ODO sensor for integrated measurements on CTDs, profiling floats, ASVs, and bottom landers. The self-contained capability will enable more high-quality dissolved oxygen and temperature measurements for a wide range of new oceanographic applications and discoveries."
