Concrete moisture meter

These meters have been used for decades to measure the moisture content in different materials and substances.

Concrete moisture meters are designed to detect moisture to a depth of 1 inch (25 mm) of a concrete slab in order to avoid the rebar reinforcement below the surface.

"[3] The results can determine the best place to put a concrete relative humidity test.

This can be anything from the density of the concrete and aggregate size to the chemical properties of the slab.

In order to ensure the equilibrated moisture will be a safe level[6] for a floor covering, a relative humidity sensor must be drilled and placed at 40%[7] of the depth of the slab.
