Ambient humidity vs. RH

[eblakewi]

How is the Relative Humidity actually being measured? I assume that there is not a trained ant inside the probe doing using a tiny sling psychrometer. And it appears that conductivity of the concrete is not being measured. So how is the RH actually being measured? If I have entered into an area of proprietary secrets, I apologize, but I could not find an answer on the rest of the web site.

Well it is quite obvious you are an extremely intelligent man Rubensgt40, by the way do you mind if I put your quote on a t-shirt that I can give to my compadres here on the forum??

I believe you have the idea down pat already. Do you have any friends you could bring on the forum?

As for regional differences in acceptable RH levels, I have not experienced such a thing. I do know that 75% is regarded as safe in the states, but I also know it is very safe in the areas I work. I haven't seen problems at 80% and probably never will. Maybe even 85% would work, but one must keep in mind that ignoring the manufacturer's recommended installation parameters will most likely void any warranty on the materials.
