CTD & Multi Channel Loggers
Submersible Multi Channel Data Loggers
RBR makes a diverse range of CTDs and other multi-channel, multi-parameter submersible loggers (sonde, recorder) for water quality measurements. Our loggers are designed for long term autonomous deployments or for profiling water columns. We offer a suite of other sensors for measuring other parameters, aside from conductivity, temperature and depth like pH, dissolved oxygen, PAR, ORP, turbidity, fluorescence, and thermistor strings. Additionally a number of derived channels are available, for example speed of sound, salinity, specific conductivity and more. The XR series can accommodate up to six sensors, while the XRX series permits 10 sensors to be installed. The -420 designates an instrument capable of 1Hz or slower sampling, while the -620 class is able to average samples internally, threshold, and profile at 6Hz.
