Product review (4 stars): Easy set up and fast delivery
I recently had our crawlspace encapsulated and wanted to see what the humidity levels were now that it's done. The company that did the work measured it at 70% and I knew that couldn't be correct so I ordered 2 Hygrometers to check for myself. I have one in the crawlspace and one in my living room Both are reading under 40% with these hygrometers.

I still don't know if they are accurate but I'm betting they are close just because our windows didn't sweat or frost during the months of February and March.

Perhaps if I have another check of the humidity I can change to 5 stars if they prove to be correct. I am hoping they are....

I like the layout of the screen. I thought it might be backlighted but I have to use a flashlight to read the one in the crawlspace, which is not a big deal.
