  • Answer:

    This logger is rated IP67 with means it's dust tight and is protected against effects of immersion from 15cm to 1 meter for up to 30 minutes.  With that said it is not what we could consider an "underwater" logger as it's not designed to be submerged for long periods. 

    If you need something for long term deployment or plan to use it exclusively for underwater use we would suggest going with something designed for that application.   You can use the "Environment" filter on the right side of the page to identify other options.
