Mounting Requirements:

It is very important that the logger housing does not become distorted when mounted. When mounting these loggers to any non-flat surface, such as rebar or buoy lines, we recommend using the included Mounting Boot (BOOT-MX2201-2202). This boot is also useful for mounting loggers so that they can be easily removed for service. Purchase additional mounting boots as needed!

Purchase an MX Data Plan to get more out of your data and access it from anywhere using the LI-COR Cloud software platform (formerly HOBOlink)! You can also purchase the MX Gateway station, which automatically sends your logger's data to LI-COR Cloud (indoor deployments).
