    Band clamps are used to attach the bottles. The SBE 55 ECO Water Sampler is designed for continuous data collection in coastal and estuarine waters, and large lakes. The SBE 55 can be used with an SBE 19, 19plus, 19plus V2, 25, 25plus, or 49 CTD.

  • Page 12: Real-Time Operation

    System description 3.2 Real-time operation The Electronics Control Module (ECM) includes a winch cable connector for real-time use. To change from autonomous to real-time operation, connect the winch cable to the ECM and the SBE 33 Carousel Deck Unit to AC power and winch slip rings. The ECO is then powered and controlled by the SBE 33.
