RBRduraturo4
The standard instrument just received an upgrade!
Infinite memory and 6x D-cells are housed in a new 100mm wide body, allowing significantly longer campaigns of temperature and/or depth measurement.
RBRsolo4 & RBRduet4 – Meet the new SL4
Still small in size, but huge in performance - meet the new range of compact instruments from RBR.
The SL4 series maintains any AA battery compatibility and USB-C connectivity, while introducing effectively unlimited memory, multi-rate sampling, and multiple data set capability. But that is not all - new features include:
Integration of RBRs turbidity (Tu) and chlorophyll-a (chl-a) sensors
Optional 2x battery extended configuration to double your deployments
Exchangeable RBR serial sensor convenience - just swap and go any RBR sensor!
