The ECO is the ideal small-boat water sampler for
coastal, estuarine, and large lake ecological monitoring. The ECO is
light and economical and can be integrated with an SBE 19,
19plus V2, 25,
It is available in a three-bottle or six-bottle configuration with 4-liter ECO
sample bottles, uniquely designed for the ECO. The ECO can
operate autonomously on internal batteries and be programmed to close bottles at
selected depths, allowing deployment using non-electrical wire or line. It also
can be used with an SBE 33 Carousel Deck Unit for
real-time CTD data acquisition and water sampling. Real-time operation
requires an electro-mechanical cable and slip-ring equipped winch.
(*Note: SBE 49 integration for real-time operation only.)
The bottle closing mechanism is a magnetically actuated lanyard release latch derived from the SBE 32 Carousel Water Sampler, with a long history of reliability and ease-of-use. Lanyards are rigged to hold bottles open when attached to the release latches. A pressure-proof electromagnet is energized on command to trigger a lanyard release, allowing the bottle to close. The ECO has one or two 3-position lanyard release assemblies. Each release assembly is connected to the ECO’s Electronics Control Module by a separate cable, allowing easy do-it-yourself expansion from a three- to a six-bottle system.
The ECO includes the Electronics Control Module (ECM), one or two lanyard release assemblies, three or six 4-liter ECO sample bottles mounted in saddle brackets and fastened with band clamps, stainless steel guard frame with integral lifting bail, and mesh panels for mounting the ECM, CTD, and other sensors that may be integrated with the CTD (e.g., dissolved oxygen sensor, fluorometer, turbidity sensor, etc.). CTD mounting brackets and interface cable, auxiliary sensors, and (for real-time operation) SBE 33 Carousel Deck Unit must be ordered separately.

WATER SAMPLER CONTROL
|Autonomous Operation (wire rope
only, no electromechanical cable required)
The ECO’s Electronics Control Module provides power to and programmable control of the water sampler:
At the end of a cast, data from the CTD and the bottle summary file from the ECO are uploaded using the software provided. Nine high-quality alkaline D-size cells (LR-20) provide several months of daily operation (rechargeable Ni-MH batteries also available).
Real-Time Operation via
The ECO’s Electronics Control Module can be connected to a winch cable for real-time use. Users can switch from autonomous to real-time operation at any time by connecting the winch cable to the ECM, and connecting the SBE 33 Carousel Deck Unit to AC power and the winch slip rings. This enables real-time CTD data acquisition and water sampler control from your computer keyboard or Deck Unit panel controls:
