Definition of material moisture
In the standard delivery state, the device measures and shows the material moisture.
The material moisture defines the amount of water contained in the material in relation
to the material´s dry weight.
Example: 0.6 kg with 0.4 kg water
The dry weight of 0.6 kg corresponds to 100 %. In relation to the dry weight, the 0.4
kg water result in a material moisture of 66,7 %.
6.2
Definition of moisture content
The moisture content readings are calculated in relation to the material’s overall mass:
M
n
:
Mass of the sample with average moisture content
M
t
:
Mass of the sample with zero moisture content
%WG: Moisture content (in accordance with EN ISO 18134-2)
Example: 1 kg material with 40 % moisture content. The total weight of 1 kg (corre-
sponding to 100%) consists of 0.6 kg (60 %) material and 0.4 kg (40 %) water.
It is possible to set the device to the calculation of moisture content at the factory. For
