Description

RBR's multi-parameter, multi-channel loggers are designed to provide you with the flexibility to select the right combination of sensors for your water quality measurements. The choice of up to ten sensors can be integrated with the logger. The loggers are available in two configurations: one for autonomous deployment and one for water column profiling. The recorders can be equipped with data and power connections to facilitate remote access or remote data acquisition. There are a number of different sensors that can be used with the recorders, for example, Conductivity, Temperature, Depth, pH, ORP (RedOx), Dissolved Oxygen, Fluorescence, Turbidity, Transmittance, PAR, and others.

Features include:

  • 240M readings
  • Up to 16Hz sampling
  • USB-C download
  • Twist activation
  • Wi-Fi ready
  • Supports 3 to 10-channel combinations
  • Realtime communication with USB, RS-232, or RS-485
  • Available Sensors: Conductivity, Temperature, Pressure (Depth), Dissolved Oxygen, Fluorescence, ORP, PAR, pH, Transmissance, Turbidity, and Voltage

Features

  • Submersible, autonomous 24-bit data logger
  • 16Hz maximum sampling rate
  • 240M readings
  • Up to ten sensors in custom configurations can be integrated
  • Sensors include Conductivity, Temperature, Depth (Pressure), pH, ORP(RedOx), Dissolved Oxygen, Fluorescence, Turbidity, Transmittance, PAR, and many others in any combination
  • C, T, D and DO are measured to WOCE standards
  • All calibration constants are stored in the logger
  • Re-calibration of many sensors may be carried out by the end-user under suitable conditions
  • 8 AA cells
  • USB-C download
  • Optional RS-232 or RS-485 serial communication allows real-time operation over long cable links using the Ruskin application
  • Mooring clamps and cages are optional and rugged transit cases are recommended
  • Deep and shallow water versions
