The DST centi-T is a miniature submersible temperature data logger. Recorded data is stored in its internal memory with a real-time clock reference for each measurement.
The self-contained temperature logger 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.
After recovering the DST recorded data is uploaded via 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 harsh environments.

Temperature calibration outside standard range
Temperature calibration outside of standard ranges or for smaller ranges is available for all products on request.
Examples of Application
DST centi-T is mostly used as a stand-alone logger for sampling temperature in underwater environments, attached to deployment lines, moorings or other gear. It can also be used for measuring temperature in soil or air. Another usage is measuring temperature values in animals. The DST centi-T can be implanted in animals. The housing is made of biocampitible material.
The DST centi-T temperature logger is used for various studies, for example:
- Temperature fluctuations in animals
- Thermistor chain in water columns
- Temperature monitoring in oceans, rivers and lakes
- Agricultural research projects
- Aquaculture studies
