Idronaut products

AISI316L Temperature Sensor (700 bar): Very fast response platinum resistance thermometer. Main application: Profiling. Titanium Temperature Sensor (700 bar): Fast response platinum resistance thermometer. Main application: Long Time Monitoring.

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 OS314 On-Line module is housed in a sealed POM cylinder provided with a transparent acrylic flow cell which is easily removed for sensor cleaning and maintenance. The sample volume of the measuring chamber is only 420 ml, which ensures a very fast response time. The measurement sensors installed in the On-Line module are manufactured by IDRONAUT. The On-Line module is controlled by an advanced miniaturized and very low power electronics that store measurements in non-volatile memory or transmit them in real-time at sampling rate of up to 28 Hz. The On-Line module can be directly connected to a data logger or personal computer by means of a wired or wireless interface. Optional interfaces allow the connection of external fluorometer and turbidity meter.

The OCEAN SEVEN 310 BOREHOLE multiparameter CTD is the result of IDROANUT’s 40-year-old experience in the design and manufacturing of high-technology borehole probes for deep groundwater profiling. The OS310 CTD multiparameter probe, which presents very small size (diameter of only 43mm), has been specifically designed for groundwater investigations through “boreholes” and uses very reliable, accurate and drift-free high-quality sensors, associated with advanced and miniaturized electronics.

The “Conductivity-Temperature Transfer Standard CT-01Plus” is a compact and rugged instrument designed for the metrology laboratories to perform calibration of oceanographic CTD probes. It combines a Primary Standard 100 ohm RPRT (Reference Platinum Resistance Thermometer), a large-sized Idronaut self-flushing cell provided with seven internal rings of fused platinum in the quartz with a microprocessor controlled high resolution and high accuracy electronic amplifier.

The telemetry portable deck unit powers and interfaces by coaxial oceanographic cables, the OCEAN SEVEN 3xx probes with a personal computer. The portable deck unit is equipped with a transceiver (modem) which allows half-duplex communication with the probe. The portable deck unit is housed in a waterproof plastic case and is provided with an internal mans rechargeable lead battery (12 VDC, 7 A/h) which permits probe operation even in the absence of the mains supply. The portable deck unit comes complete with an international battery charger: 115/220 VAC +/- 10%, 50-60 Hz +/- 5%. Telemetry power supply: 30 VDC (max 0.3 A @ 12V). Dimensions: 340 x 300 x 16 mm. Weight 6.5 Kg.
