I'm actually talking about logging ambient conditions. Because we have heard that the above slab humidity and temp can affect rh in the slab I feel I have to pay attention to where the RH/Temp in the room is going to have an idea if the Rapid RH number is accurate or artificially high/low from the ambient above slab conditions.
Oh heck, I've had one from Radio Shack for years that I sometimes hide on sites. The ones that you can link up to your pc are better.
