The RBRduo³ C.T and the RBRconcerto³ C.T.D are uniquely designed to determine salinity by measuring the conductivity and temperature of water. Conductivity measurements are performed using a rugged inductive cell that can be frozen into ice. Equipped with a pressure channel, the RBRconcerto³ C.T.D can also derive depth, density anomaly, and speed of sound.
The RBRduo³ C.T and the RBRconcerto³ C.T.D instruments facilitate optimal measurement schedules, whether moored, towed, or profiling. Both instruments come with a Wi-Fi module and twist activation. Variants in titanium housing are available for deep applications (| deep), designed to endure harsh conditions. Large storage capacity and reliable battery power facilitate long deployments with higher sampling rates. Downloads are quick with USB-C. A dedicated holder makes it simple to replace desiccant before each deployment. The calibration coefficients are stored with the instrument, and only one software tool, Ruskin, is required to operate it. Datasets can be read directly in Matlab, or exported to Excel, OceanDataView®, or text files.
