Small implantable temperature data logger DST milli-T

Key features:

  • Biocompatible housing, ideal for implantation in animals for temperature monitoring
  • Waterproof data logger up to 90 bar (900 m)
  • Small dimensions 39,4 mm x 13 mm, 9,2 g
  • Large memory size of 87,000 measurements
  • Long battery life, typically 5 years

Description

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.
