RBRduet³ T.ODO compact temperature and oxygen logger

RBRduet³ T.ODO Temperature and Oxygen Logger

RBRduet³ T.ODO:
temperature and optical dissolved oxygen

Our most compact, lightweight, and versatile dual-channel logger.

High accuracy
Optical stability
Long deployments
Depths up to 6000m
One AA battery
USB-C download
Compact and lightweight
Cabled RBRcoda³ T.ODO variant available

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.
