SBE 16plus-IM V2 SeaCAT CT(D)

The SBE 16plus-IM V2 SeaCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with Inductive Modem (IM) interface designed for long-duration deployments on moorings. It supports numerous auxiliary sensors (dissolved oxygen, turbidity, fluorescence, PAR, etc.) with six A/D channels and one RS-232 data channel. The 16plus-IM V2 has internal batteries and memory.

Data is recorded in memory and can also be output in real-time in engineering units or raw HEX. Battery endurance varies, depending on the sampling scheme; nine alkaline D-cells provide power for 290,000 samples of C and T.

• Moored Conductivity, Temperature, Pressure (optional), and up to seven auxiliary sensors, at user-programmable intervals (10 seconds to 4 hours).
• Inductive Modem (IM) interface, internal memory, and internal alkaline batteries.
• Expendable anti-foulant devices and optional pump for bio-fouling protection.
• Depths to 600, 7000, or 10,500 m (data transmission rated to 8000 m).
• Seasoft© V2 Windows software package (setup, data upload, and data processing).
• Next generation of the SeaCAT family, field-proven since 1987.
• Five-year limited warranty.

• Inductive Modem (IM) system provides reliable, low-cost, real-time data transmission for up to 100 IM-enabled instruments using plastic-coated wire rope (typically 3x19 galvanized steel) as both transmission line and mooring tension member. IM instruments clamp anywhere along the mooring, which is easily reconfigured by sliding and re-clamping instruments on the cable. In a typical mooring, an Inductive Modem Module (IMM) in the buoy communicates with IM instruments and interfaces to a computer/data logger (not supplied by Sea-Bird) via RS-232. The data logger is programmed to poll each IM instrument for data, and sends the data to a satellite link, cell phone, etc.
• Unique internal-field conductivity cell permits use of expendable anti-foulant devices, for long-term bio-fouling protection.
• Aged and pressure-protected thermistor has a long history of exceptional accuracy and stability.
• Optional pressure sensor with temperature compensation is available in eight strain-gauge ranges (to 7000 m) and eleven Digiquartz® ranges (to 10,500 m).
• Optional pump runs for each sample, providing improved conductivity and plumbed auxiliary sensor response, bio-fouling protection, and correlation of CTD and auxiliary sensor measurements.

• Plastic (600 m) or titanium (7000 or 10,500 m) housing (data transmission rated to 8000 m).
• XSG/AG or wet-pluggable MCBH connectors.
• No pressure, or strain-gauge or Digiquartz® pressure sensor.
• SBE 5M pump for pumped conductivity; or SBE 5P or 5T pump for pumped conductivity and auxiliary sensor(s).
• Auxiliary sensors — dissolved oxygen (SBE 63 Optical DO Sensor or SBE 43 [membrane-type] DO Sensor), fluorescence, radiance (PAR), light transmission, turbidity, etc.
• Battery pack kit for lithium batteries (batteries not supplied by Sea-Bird).
