Function / Application
This material moisture measuring device operates in accordance with the resistance and capacitive
measuring principle. The capacitive measuring principle uses 2 conductive rubber contacts on the
underside of the device to determine the moisture-dependent dielectric permittivity of the material
and calculate the relative material moisture as a percentage based on internal material-dependent
characteristics. The resistance measuring principle determines the moisture-dependent conductivity
of the material when the test prods make contact with the material, compares the result against the
stored material-dependent characteristics and calculates the relative material moisture as a percentage.
The device is used to determine the moisture content in wood and building materials with the aid of the
corresponding measuring method. An additional pop-out sensor on the side of the device determines
the ambient temperature and relative humidity and calculates the resulting dew point temperature.
The integrated building materials characteristics correspond to the stated construction materials
without admixtures. Construction materials will vary from manufacturer to manufacturer, due to the
! way in which they are produced. This is why, in the event of different product compositions or un-
familiar construction materials, a one-off comparative moisture measurement should be taken using
methods that can be calibrated (e.g. kiln-drying method). If different measured values occur, they
should either be viewed relatively or the index mode for moisture/drying behaviour should be used.
