  • Answer:

    Yes, this product can be used in crawl spaces.  Something to keep in mind is that these loggers have to be plugged into a PC running software in order to view the recorded data so if the crawl space isn't easily accessible and you plan to download your data frequently this might not be the best option.  If that is the case I would suggest looking at a wireless logger that you can access from outside the crawlspace.
