Nautilus - Model RBR -Multichannel Ocean Data Loggers
The RBRconcerto³ can be fitted with up to 5 channels whilst the RBRmaestro³ can be fitted with up to 10. Equipped with big storage capacity and USB-C download, they are optimized for long deployments with high sampling rates. The RBRbrevio³ C.T.D is short in stature but tall on performance. With world-class sensor accuracy, a sampling rate up to 32Hz, and realtime data output, the RBRbrevio³ is the smallest CTD to integrate into your towed vehicle, AUV, ASV, or ROV.

Conductivity is measured with an inductive sensor, suitable for deployment in marine, estuarine, or fresh water. There are no exposed contacts, which avoids susceptibility to corrosion, and the housing may be frozen into ice without damage. It is characterized for the mechanical effects of both temperature and pressure to allow for accurate correction in salinity derivation. These coefficients are provided for customers who prefer to calculate their own corrections. In addition, it is suitable for use outside the usual realms of PSS-78 practical salinity scale, in applications such as desalination brine monitoring. The conductivity readings are temperature-corrected.
The temperature sensor is built and calibrated in-house using an aged thermistor. The temperature channel is calibrated an accuracy of ± 0.002°C (ITS-90) over the range -5 to +35°C. Extended range calibrations are available.
Pressure is measured with a piezo-resistive transducer with nickel based super alloy diaphragm to avoid corrosion. Accuracy is 0.05% of the full scale rating and achievable resolution is 0.001%.
