Insert probes and take a reading with the RH meter. The thermo-hygrometer’s reading of the humidity in the concrete slab will tell you how much excess moisture is present deep in the slab that might evaporate up through the surface. This can tell you if the concrete is likely to damage the materials above it or suffer other problems.
Morris Brothers manufacture a wide range of dispensing systems to suit the production of hydraulically pressed concrete products. The volumetric is a simple, but effective design and has been widely used in the industry since the 1970’s.

Concrete moisture meters measure only the top inch at most and this area is drier than the concrete further down. Once a floor covering has been installed the moisture in the slab equilibrates . In order to ensure the equilibrated moisture will be a safe level for a floor covering, a relative humidity sensor must be drilled and placed at 40% of the depth of the slab.
