Relative Humidity - RH measurement

Air, in our normal environment always holds humidity. The number of water molecules in the air can vary substantially, e.g. it can be as dry as in a desert or as humid as in the tropics. There is an upper limit to the amount of humidity which air can hold at a given temperature. Beyond this limit, saturation will occur. If for some reason the humidity level is pushed up to this limit, condensation occurs and fog or water droplets form. Relative humidity tells you what percentage of this maximum amount of humidity is present in the air.

High levels of ambient humidity can be warning sign at inspection jobs, and RH is also a major concern when installing a wood floor over a concrete sub-floor..
