Why Relative
Humidity Testing?

For successful flooring projects, it is crucial to measure moisture below the surface of the concrete slab. Other tests are surface-based and do not give reliable results. For example, the anhydrous calcium chloride test measures only the moisture vapor emission rate coming from the slab’s surface. It tells you nothing about the moisture condition deeper in the slab. Only the in situ relative humidity (RH) test is scientifically proven for accuracy and reliability.

“The process behind the Rapid RH is solid. We went to Rapid RH because the accuracy is certified and it doesn’t need to acclimate past its initial point. We could stick [the sensor] in there, read it and trust it.”
