MISS Sampling System

MISS Sampling System

This MISS sampling system accept up to six (6) NISKIN bottles of different capacities (0.8, 1.5, 2.1 Liter each) and comes complete with a RS232/RS485 digital interface and a simple protocol that allows to control the bottle firing operations. The NISKIN bottles are closed in sequence starting from bottle 1 to bottle 6. The MISS integrates a rechargeable battery pack to power the sampling system and the interfaced CTD. Instead of a bottle it is possible to install an IDRONAUT OCEAN SEVEN CTD, (OS310, OS316Plus or OS320Plus) which takes control of the MISS sampling system operations and provides real-time measurements from the installed sensors like but not limited to: Pressure, Temperature, Conductivity, Salinity, pH, Dissolved Oxygen, Redox, Turbidity, Chlorophyll-a, Phycocyanin, Phycoerythrin.
The OCEAN SEVEN CTD can fire (close) the NISKIN bottles autonomously in function of Time, Pressure steps or if a certain environmental condition is detected, like among others:

  • The increasing of seawater turbidity;
  • The modification of one of the physical (CTD) or chemical (pH, DO2) seawater properties.

Moreover, it is possible to fire the bottles in real-time when the CTD is controlled through the IDRONAUT data telemetry system.

  • 6x NISKIN Bottles 0.8, 1.5 or 2.1 Liters each.
  • Maximum depth: 1000 m.
  • External power supply 12VDC @ 30 mA.
  • Internal rechargeable battery pack (12x1.2V NiMH cells, 5Ah), endurance about 80 hours with OS310 CTD.
  • Interface RS232 or RS485 (9K6 bps).
  • Simplified communication protocol which allows integration with third part of the MISS as an OEM off-the-shelf component.
  • Weight: about 17 Kg (5 bottles without CTD).
  • Height: 90 cm including the hanging rod and the lower titanium protective cage.
