Optimal Moored CTD
Moored Conductivity, Temperature, and Pressure (optional), at user-programmable 6-sec to 6-hour intervals.
Flexible Deployment Options
Internal memory and battery pack.
Inductive Modem Telemetry
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.
Integral Pump
Pump runs for 1 second for each sample, providing improved conductivity response and bio-fouling protection.
