Various sensors:
Underwater temperature and depth
Salinity sensor (conductivity)
Pitch and roll sensors (tilt angle)
Underwater compass logger   

DST series is specially designed for tagging fish for analysing fish migration, distribution, feeding behavior, vertical  and horizontal movements. The DSTs are also ideal as a stand-alone logger for temperature and depth recordings in oceans or fresh water or as for other liquid temperature-pressure measurements. The housing is made of bio-compatible material, which does not endanger the health of the tagged animal. The non-transparent housing ensures that the sunlight does not affect the measuring and therefore provides more reliable data.   

DST Product Series Overview

Submersible temperature recorders designed for use in oceans, rivers, and lakes, robust environment and high temperatures

Starmon mini has an all plastic housing that is robust and does not corrode in the sea.  For more extreme pressure the Starmon mini is available in non-corrosive titanium housing. Battery is replaceable with the use of soldering iron.  Long battery life and large memory size.

The DST loggers are available as low cost temperature loggers. Battery is not replaceable.

Temperature recorders overview

Sensors: GPS code, temperature and depth
Memory size: Total memory size 87164
Battery life: Depending on frequenqy of measurements (approximately up to 3-4 years)
Depth: Down to 3000m depth 

DST GPS measures temperature, pressure (depth) and listens to a GPS signal from sonar.

 Data is stored in a non-volatile internal memory. All recordings are time related, utilising a real time clock inside the recorder.

The cost effective and small size construction of the DST GPS archival tag has been possible by carefully selecting modern micro-miniature electronic components and successful sensor development at Star-Oddi.

The DST GPS fish tag has been equipped with the unique user specified features for optimising the tag's performance when receiving and storing in its memory the fish GPS position.

The Underwater Tagging Equipment gives the following advantages

• The UTE is specially designed for tagging deepwater fish that cannot survive changes in pressure and surface temperatures
• It prevents the need for hauling the fish to the surface for tagging and release
• Less time is spent in handling the fish, which leads to increased tagging efficiency
• Fish is tagged in its natural environment, avoiding stress factors as pressure and temperature changes and therefore decreases tagging mortality.
