Manuals and Resources


  • Answer:

    The EL-USB-1 is not designed for use underwater or submersion.  The logger is rated IP61, which means it's dust tight and protected against dripping water.

    If you need something that can be submerged we would suggest looking at loggers designed for underwater use.

    If you go to our temperature logger page and use the "Shop By" options to filter you will see an option under the heading "Environment" that says "Underwater".  These loggers would be better suited for your application.

    Here is a link to our temperature loggers - https://www.microdaq.com/data-loggers/temperature.php

    You will still need to use the filter options noted above to narrow it down to submergible loggers.

  • Answer:

    The logger doesn't come with a calibration certificate.  The logger will function with  the same accuracy whether you purchase the calibration service or not.  The calibration service is just a validation of accuracy of each specific logger you purchase.  It doesn't affect how the logger works so unless you are required to have a calibration certificate on file you wouldn't need to purchase one.

  • Answer:

    This logger can operate down to -35°c (or -31°F).  Battery life will be on the shorter side of the estimated range when used at these low temperatures for any extended period.
