The RBRsolo³ D and RBRduet³ T.D, |tide and |wave, take averages of pressure readings over extended periods of time, providing accurate tide level data. Intermittent and continuous wave bursts allow for obtaining wave characteristics (wave energy, H1/3, T1/3, Tave and Have) and detecting infrequent phenomena, like boat wakes.

These loggers are built for long, accurate field use with low effort. Delivering high accuracy in a compact, field-ready form factor, it combines lab-grade performance with deployment simplicity. USB-C enables fast configuration and data download, while support for standard AA battery chemistry provides global power options. 

Paired with Ruskin software for intuitive setup and retrieval, these loggers are designed for exceptionally long deployments, using RBR’s latest ultra-low-power electronics to maximize endurance without compromising precision. Data are stored in RSK format and are accessible using RBR’s open Python and MATLAB toolboxes, enabling direct integration into workflows and automated processing pipelines. Ruskin provides Excel exports and publication-ready charts in PNG and PDF formats, ensuring straightforward reporting, analysis, and archiving.
