Rh Test

Relative Humidity Test
Relative Humidity (Rh) (ASTM F-2170) tests measure the humidity in the slab at a depth of 40% and gives values in percentages. Rh testing offers insight into the total moisture content within the slab providing the ability to predict future vapor drive. Rh testing is also an excellent way to conduct trending analysis using the same drilled location over and over again. Rh is less susceptible to ambient temperatures and humidity therefore allowing for more accurate readings during new construction.
