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.

1 RBR calibrates radiometers with NIST traceable references.
2 Out-of-band rejection and resolution are wavelength dependent for narrow-band radiometers.
3 Other CWL options within the 400-1100nm range are available upon request. Contact RBR for more information.
4 Resolution is wavelength dependent for narrow-band radiometers.
Note: Dark offset is internally temperature-compensated.
