Box of Vintage Foxboro Humitex Charts

Apparently these round charts are used in some capacity to record environmental conditions from a circular chart recorder. Or something like that. I was online for over an hour reading about them and still don't really know what they are used for. But I am sure there are some home-weathermen out there that would love to have them! Original box w/ 100 charts. Not sure if it is a complete box but it looks pretty full.
