Wood: The measured depth in wood is 30mm maximum but does vary
somewhat with differing wood densities. Measurements made on thin wood
boards should, if possible, be made on a stack of these boards as otherwise
the measurement will be too low. Measurements made on installed wooden
structures are inuenced by the structural conditions and their chemical
treatments (e.g. paints) with various materials. Thus such measurements
should only be viewed relatively.
Maximum accuracy is achieved between 6% and 30% wood moisture. In very
dry wood (< 6%) irregular moisture distribution can be detected, in very wet
wood (> 30%) saturation of the wood bres begins.
Material relative moisture reference values, in %, for use with wood:
– Outdoor usage: 12% … 19%
– Use in unheated rooms: 12% … 16%
– In heated rooms (12 °C … 21 °C): 9% … 13%
– In heated rooms (> 21 °C): 6% … 10%
This moisture measuring device is a sensitive tool. This means that the
measurement results may be subject to slight deviations when someone
touches the device with their hand or when contact is broken between
the device and the material being measured. However, contact with the
user’s hand forms the basis for calibrating the measuring device, so we
recommend holding onto the device whilst taking your measurements.

Functional and operational safety is only warranted when the instrument
is operated within the specied climatic conditions and is only used for
those purposes for which it is designed. The assessment of measurement
results and actions taken as a consequence lie in the user‘s scope of
responsibility, depending on the given type of work.
