RBRbrevio³ C.T.D

Smallest C.T.D for integrated applications

The RBRbrevio³ C.T.D is short in stature but tall on performance. With world-class sensor accuracy, a sampling rate up to 32Hz, and realtime data output, the RBRbrevio³ is the smallest CTD to integrate into your towed vehicle, AUV, ASV, or ROV.

Description

The RBRbrevio³ C.T.D conductivity, temperature and pressure logger is our C.T.D logger built on the years of experience RBR has creating reliable and easy-to-use instruments. The instrument generates salinity and speed of sound internally. A self-contained, accurate and autonomous submersible instrument, it can be deployed for a period of up to 5 years at 1-minute sampling intervals and data is retained in memory even without batteries.

Features Include:

  • 240M readings
  • Standard sampling up to 1Hz
  • Up to 32Hz sampling
  • USB-C download
  • Realtime communications
  • Twist activation
  • Wi-Fi ready
  • deep options for down to 6000m
