  • High temperature logger version available
  • Description

    Small and handy  

    This small autonomous depth and water temperature recorder is ideal for placement in different aquatic conditions, with dimensions of only 39.4 mm x 13 mm. Adding the plastic protective housing makes it easy to mount on submersible gear and moorings.

    Application

    The small yet high performing depth temperature logger is used for:

    • Ecosystem research – water level and temperature  monitoring in oceans, rivers and lakes
    • Fisheries research – gear behavior and fishing depth logging
    • Time depth profiles on underwater gear
    • Quality monitoring – temperature and water depth of geothermal boreholes and wells
    • Fish and marine animals tagging – more information click here.

    Flexible mounting with protective housing

    A plastic protective housing is available, recommended when fastening the logger to submersible gear and moorings. It has attachment holes on both ends.

    Pressure sensors from low to higher ranges

    There are various pressure ranges available. Pressure calibration ranges selectable up to 50 m, 100 m, 250 m, 500 m or 800 m. The shallower the range the better the pressure resolution and accuracy.

    Long life in a small logger

    The battery life is 3.5 years, measuring at 5 minute interval. Recorded data is stored in the logger‘s internal memory with a time stamp for each measurement.

    Large memory size

    The logger has large memory capacity 699000 paired temperature and depth measurements, or ca 1.4 million measurements in total.

    High temperature logging

    The standard temperature range is -1°C to +40°C (30°F to 104°F).  Calibration range can be extended upon request, up to max 85°C (185°F).
