RBRvirtuoso

RBRvirtuoso single channel loggers offer flexible measurement schedules, sampling up to 1Hz, large memory, extra power for extended deployments, and USB 2.0 download for large data files. Optional features include sample averaging, up to 12Hz fast sampling, twist activation, Wi-Fi connectivity, and extended memory.

The RBRvirtuoso makes it easy to configure the optimum sampling regime for your measurements. The large data storage capacity, and fast download ability facilitate long deployments with higher sampling rates.

The RBRvirtuoso is available in a standard body or extended body with more power for long deployments. Almost every sensor from RBR can be interfaced to the RBRvirtuoso. Dataset export to Matlab®, Excel®, or text files make post processing with your own algorithms easy.
