RBRsoloยณ DO, Tu, and PAR: single-channel loggers
The RBRsoloยณย instruments can integrate a selection of third-party sensors, such as dissolved oxygen, turbidity, and PAR. Low power consumption, large memory, and ability to endure harsh conditions make the RBRsoloยณย instruments a perfect choice for many oceanographic applications.
- Long deployments
- Compact and lightweight
- One AA battery (alkaline or lithium iron)
- USB-C download
- Cabled RBRcodaยณย variants available
Features & Configurations
The RBRsoloยณย instruments with DO, Tu, and PAR sensors 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, OceanDataViewยฎ, or text files.
