The DST centi-TD is a miniature underwater data logger with temperature and pressure (depth) sensors. Recorded data is stored in the loggers internal memory with a real-time clock reference for each measurement.
The DST centi-TD is supported by the SeaStar software and the Communication Box which serves as an interface between the logger and a PC. Communication between the logger and the Communication Box is wireless.
In SeaStar, the user sets the start time, start date and sampling interval before starting the recorder. Up to seven different intervals can be set for the same measurement sequence. This is especially useful when more frequent measurements are needed at a certain time period.
With default programming temperature and depth are recorded as pairs. Optionally, the two parameters can be set separately as primary and secondary parameters with different sampling frequency. That way memory partitioning can be customized according to individual preferences.
After recovering the DST recorded data is uploaded to SeaStar where results are displayed both in graphic and tabular form. After retrieving the data, the DST can be re-programmed and reused as long as the battery lasts.
A set of Communication Box and SeaStar software needs to be purchased with the first order.
Star-Oddi also offers protective logger housings for use at fixed locations or in harsh environments.
Examples of Applications:
DST centi-TD can be used as a stand-alone logger for recording depth and temperature in ocean and freshwater environments. The DST can be fastened to fishing gear, deployment lines, cables, moorings or other underwater equipment, collecting valuable data. The DST - TD is ideal for tagging fish and marine animals, externally or internally with implantation providing information on e.g. fish behavior and migration.
The DST centi is suitable for studies in e.g.:
Marine Animal tagging
Fisheries research
Oceanography
Marine biology
Ichthyology
Hydrology
Ecosystems research
