Greatest accuracy is reached between 6 % and 30 % material
moisture. In very dry wood (< 6 %) irregular moisture distribu-
tion can be detected, in very wet wood (> 30 %) saturation
of the wood Öbres 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 %
Example:
100% material moisture for 1 kg of wet wood = 500 g water.
Functional and operational safety is only warranted when
the instrument is operated within the speciÖed 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.
