RBRsolo³ PAR and RBRsolo³ rad compact PAR and narrow-band loggers
Product Number：RBRsolo³ PAR and RBRsolo³ rad compact PAR
The RBRsolo³ PAR and RBRsolo³ rad logging radiometers feature a wide dynamic range, optimized cosine response, and excellent low-light detection, making them ideal for both moored and profiling applications. Both instruments feature a rugged, low-power design that allows for long deployments with a single AA battery.

The RBRsolo³ PAR provides uniform response to light in the PAR spectral range, while the RBRsolo³ rad is available in a variety of narrow-band light channels and channel widths. Large storage capacity and reliable battery power facilitate long deployments with higher sampling rates. Downloads are quick with USB-C. 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, OceanDataView®, or text files.
