The RBRvirtuoso³ and RBRduo³ instruments can integrate almost any sensor from RBR, offering high accuracy, flexible schedules, USB-C download, Wi-Fi communication, and twist activation. Variants with pressure, temperature, radiometer, PAR, and turbidity sensors are also available in titanium housing for deep applications (| deep), designed to endure harsh conditions.
The RBRvirtuoso³ and RBRduo³ instruments facilitate optimal measurement schedules, whether moored, towed, or profiling. 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.
