Conductivity, Temperature and Depth Salinity Data Logger

Data Storage Tags

DST CTD logger is the smallest salinity and temperature monitor on world market. The Conductivity, Temperature and Depth Logger is especially designed as a archival tag for analysing fish migration, distribution, feeding behavior, vertical and horizontal movements. DST CTD is ideal for research on marine animals as well. It weighs only 12g in water and 19g in air, the size is 15 mm x 46mm. The DST CTD memory can store up to 43,582 measurements per sensor. The DST CTD Logger is best when Depth is not constant and measuring of Depth or Pressure is required.

The small conductivity loggers are also used as CTD monitor or as a conductivity and temperure monitor whereas they are also ideal as stand-alone monitors for sampling in the ocean. They can for example be fastened to fishing gear, collecting valuable data. A protective housing for the DST CTD is available.
