DST centi-T temperature logger
Submersible underwater temperature logger with long battery life and large memory

Overview:
Sensor: Temperature (optional: pressure/depth, pitch & roll, salinity)
Memory size: 87,000 measurements (optional memory increase to 232,000 measurements)
Battery life: 5 years
Accuracy: +/-0.1°C
Depth survival: Down to 3000m

The DST centi-T is a miniature underwater temperature recorder.  Data is stored in memory and all measurements are time related, utilising a real time clock.  Since the DST centi-T is larger in size than the other DST's, it has a longer battery life and larger memory size than other DST's.

Overview

  • Ideal as a stand-alone logger for environmental studies or for underwater temperature recordings
  • Ideal as temperature and depth logger for mooring applications or in boreholes
  • Available with a plastic protective housing
  • Used in fisheries research, oceanography, ecology and marine biology
  • The non-transparent housing ensures that sunlight does not affect the measurements and providing more reliable temperature data
  • Weight is only 19g in air and 12g in water
  • Size is only 15mm x 46mm
  • Temperature range -1°C to +40°C (30°F to 104°F), outside ranges available upon request
  • Depth range can be selected up to 3000m (300 bar)
  • Long battery life of 5 years (typical)
 
 

Easy to use

DST centi-T is supported by the SeaStar software for Windows, and a communication box which connects to a computer. All communications and data transfer is wireless via the communication box. The DST is inserted into the box for establishing communication, using the SeaStar software. Before use the user sets the sampling interval and start time of recordings. The data is retrieved using the communication box and SeaStar software. The logger can be re-programmed and reused as long as the battery lasts.
