Features & Configurations
The RBRsoloยณย Tโ|โdeep, RBRsoloยณย Dโ|โdeep, and RBRduetยณย T.Dโ|โdeepย in titanium are small but incredibly strong. Deployable to the bottom of the Marianas Trench, they provide accurate and stable measurements in the most challenging environments. Low power consumption allows for extended schedules on a single battery.
The RBRsoloยณย Tโ|โdeep, RBRsoloยณย Dโ|โdeep, and RBRduetยณย T.Dโ|โdeepย are designed to endure harsh conditions. Titanium housing resists all forms of marine corrosion. Specialized circuitry ensures exceptional signal-to-noise ratio.
Large data storage capacity and reliable battery power facilitate long deployments with higher sampling rates. Downloads are quick with USB-C.ย A dedicated desiccant 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, OceanDataViewยฎ, or text files.
