The DST milli-T is a small waterproof temperature data logger. Recorded data is stored in the logger‘s internal memory with a real time reference for each measurement.
The DST milli-T is supported by the SeaStar and Mercury softwares and the Communication Box (data reader) which serves as an interface between the logger and a PC. Communication between the logger and the Communication Box is wireless.
In the software, the user sets the start time, start date and sampling interval before starting the recorder. After the measuring period the recorded data is uploaded into a PC computer through the Communication Box. Results are displayed both in graphic and tabular form in the SeaStar software. After retrieving the data, the DST can be re-programmed and reused as long as the battery lasts. Battery life can be several years, depending on sampling interval and usage. Battery is not replaceable.
A set of Communication Box and SeaStar (or Mercury) software needs to be purchased with the first order.
Star-Oddi also offers a protective housing for the DST which protects the logger when used in harsh environments and gives more flexible mounting options.

Features on Request
DST milli-T, DST milli-TD and DST milli-L (with pressure sensor) are available with an extended memory capacity (FLASH) that can store up to 682,000 temperature measurements.
Temperature calibration outside standard range
Temperature calibration outside of standard ranges is available upon request.
Examples of Application
The size, shape and biocompatible material of the DST milli-T makes it ideal as an implant for animals (land or aquatic) for monitoring temperature fluctuations. The DST milli-T can be used as a stand-alone logger for temperature measurements underwater, soil or air. The temperature loggers can for example be attached to moorings, deployment lines or strings to form a thermistor chain underwater.
The DST milli-T is suitable for various studies, for example:
- Animal temperature monitoring
- Study of thermoclines in water columns
- Ecosystems research
- Temperature measurements in liquids, vials etc.
- Pharmaceutical research studies
- Packaging industry
- Transportation, tracing temperature conditions of shipments
- Temperature measurements in air or soil
