Ben - If you're referring to the La Crosse Thermometer/Hygrometer, I've had one sensor in the cave measuring around 90%RH for most of the time with a temp around 54-57 F. The cheeses in there are waxed or vacuum-sealed and there is no added moisture such as a rag hung across the fans. The fans run continuously to circulate the air inside anyway. I have to periodically wipe the walls down to clear the moisture and any mold that starts to show. I wipe with paper towels and then sweep with a Clorox antibacterial towelette.
I have a second sensor placed outside in the weather as a sanity check. It has been cold and rainy for the past couple weeks here in the Pacific Northwest. Even when the temp is low and it is raining, the sensor measures around 94%RH
. Hello?! It's raining...shouldn't it be reading around 99%RH?
So there it is. I think after playing around with these things for a while, I am convinced it's not that far off from using a Ouija board. If you put them all side by side, they would all register something different. I
know because I put the three of them that I have side by side and none of the temps or RH readings matched. Now I'm strictly talking about the lower end devices. I would expect that if you ponied up the cash for a several hundred dollar unit, you might expect to get tighter performance. But then, who's going to do that for what we use these things for? Not this cheeser.
Right now while I type this my cave out in the garage is measuring 55.9F/88%RH on the La Crosse weather station in front of me. When I push the button to check readings outside: 41.9F/82%RH. The deck outside is wet from the rain. 11:20PM.
Hope that gives you some more data to ponder...
