RBRvirtuoso³ / RBRvirtuoso³|deep

RBRvirtuoso³ single channel loggers offer flexible measurement schedules, sampling up to 32Hz, large memory, extra power for extended deployments, twist activation, and USB-C download for large data files. Optional features include Wi-Fi connectivity, and external data and power connector with USB, RS-232, or RS-485. The RBRvirtuoso³|deep variant is available to explore up to 10,000m deep.

The RBRvirtuoso³ 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.

Almost every sensor from RBR can be interfaced to the RBRvirtuoso³ Dataset export to Matlab®, Excel®, or text files make post processing with your own algorithms easy.
