The RBRduo is our totally redesigned new two channel logger built on the years of experience RBR has creating reliable and easy-to-use instruments.

Main features:

  • Store over 25 million readings internally.

  • True USB 2.0 speed and convenience.
  • RS-232 and RS-485 support for telemetry and long cable usage.

  • Longer deployments with eight CR123A batteries.

  • Improved instrument design
  • High accuracy measurements.
  • New microprocessor, real-time operating system, sophisticated power management, and USB and serial connectivity. 

  • Mechanical redesign to reduce the complexity of the internal parts and more efficient use of the space available.
  • Unique desiccant holder in the battery end cap, making it easier to use.

RBR's small, autonomous, dual channel submersible loggers (sondes, recorders) measure temperature and pressure or temperature and dissolved oxygen. The loggers provide excellent accuracy coupled with the capability to operate in harsh conditions and for long deployments.  The RBRduo series logger can opperate in up to 740m of water;  make up to 25 million measurements; be deployed for over 5 years on one set of batteries at 1 minute sampling intervals and its USB2.0 interface means that data downloading is faster than ever before.  Also available is the deep water 2050 series titanium logger that can operate in up to 10,000m of water.
