Features & Configurations
The RBRduraturo4 delivers high-accuracy measurements with flexible sampling schedules and a significantly extended battery life. Sampling rates of up to 32Hz support data-intensive acquisition of raw temperature and pressure. By averaging pressure measurements over extended intervals, the instrument provides precise tide-level data. Configurable intermittent and continuous wave-burst sampling enables the characterization of wave conditions—including wave energy, H1/3, T1/3, Tave, Have to support the detection of infrequent events such as vessel wakes.
