Features & Configurations
The RBRduet³ T.ODO is a compact and rugged self-contained logger with two channels. It ensures high stability during extended deployments where accurate dissolved oxygen concentration and oxygen saturation measurements are critical.
The RBRduet³ T.ODO is a perfect instrument for a wide variety of applications including oceanographic moorings, fishery studies, benthic pods, AUVs, gliders, and profiling floats.
The | fast variant (1s time constant) variant is well suited for profiling applications. The | slow (30s time constant) version has a protective layer to facilitate automated cleaning by a wiper to keep it biofouling free during long-term moored deployments.
