Idronaut - Model OCEAN SEVEN 316S -CTD Multiparameter Probe
Self-Recording, Profiling, Realtime Telemetry 7000m, Multiparameter. The OCEAN SEVEN 316S CTD multiparameter probe is equipped with the IDRONAUT full ocean depth long-term stability sensors, central to which, is the high accuracy seven-platinum-ring quartz conductivity cell. The OS316S does not require pump or any other external device to flush the sensors, which minimizes its power consumption and allows the use in Arctica and Antarctica. For added flexibility, the OS316S can be easily interfaced/integrated on buoys, ROVs and AUVs, thus making this probe an ideal choice for both on-line profiling and self-recording moored applications. Optional data telemetry is available for on-line full ocean depth, real-time communications. The OS316S can optionally accommodate analogue and digital inputs dedicated to interface external sensors.
The high accuracy seven-platinum-ring quartz conductivity cell (patented) can be cleaned in the field without the need for re-calibration. This unique quartz cell employs a large diameter (8mm) and a short length (46mm) to guarantee self-flushing and no clogging after long-term deployment even in biologically active waters. Furthermore, optionally two UV-LED (Ultraviolet, 280 nm @500μW, Light-Emitting Diode) are integrated into the conductivity cell, sterilizing the sample under measurement, thus avoiding the early growth of biofouling inside the quartz measuring cell.
Features a very fast platinum resistance thermometer (response time: 50ms). Negligible self-heating effect. Optionally combined C/T sensor featuring a 7ms fast thermistor (20ms after processing) integrated in the conductivity cell is available upon request.
Allows storage of up to 300M dataset, each one being composed of the reading of all installed sensors plus the date & time, using the internal 4 GByte data memory. The OS316S communicates at a default speed of 38k4 bps, thus keeping data uploading time to a minimum.
