The RBRduo³ BPR logger is a dual channel logger built on the years of experience RBR has creating reliable and easy-to-use instruments. The RBRduo³ BPR is a submersible depth logger that is self-contained, accurate and autonomous.

Main Features
  • 240M readings
  • Short integration times with 10ppb resolution
  • 0.01% accuracy
  • Long term stability
  • USB-C download
  • RS-232 and RS-485 support for telemetry and long cable usage

The depth channel of the RBRduo³ BPR is calibrated to an accuracy of ± 0.01% full scale Calibration constants are stored in the logger and recalibration is easily carried out by the end-user. The RBRduo³ BPR is available to depth ratings up to 7000m.

Each unit employs Paroscientific Digiquartz® absolute pressure gauge, with ranges selectable from 10 dBar (10 metres of water) to 7,000 dBar (7000m) making the unit suitable for a wide range of applications from borehole testing and groundwater monitoring to deep ocean. For groundwater measurement, a barometric reference may be used to record the atmospheric pressure over the local area.
