GROMMET-5 Replacement Grommets (5-pack), for use with MX2001

For use with HOBO MX2001 water level loggers deployed in high-humidity 2-inch wells. To ensure reliable performance, the grommet isolates the MX2001's barometric pressure sensor port from moisture in the well. When deploying MX2001 loggers in other size wells, users can add adapters and a short length of 2-inch PVC pipe. Full instructions for using grommets can be found in the HOBO MX2001 user manual.
