5 Principles of the measurements
5.1 Moisture rating ( WET - MEDIUM - DRY )
In addition to the measuring value there is a moisture rating via bar graph:
Therefore the determination „wet‟ or „dry‟ is easy and comfortable for most applications and has no
longer be deduced from literature and tables.
However, this rating can only be a first approximate value, because factors like the ap-
plication field of the measured material have to be taken into account for the final rating.
Experience and knowledge can only be supported by this instrument, not replaced!
5.2 Moisture
u
and water content
w
Either moisture u or water content w is needed according to the application. The BaleCheck 100 is
supposed to be used the unit moisture u (relating to oven-dry mass). In some cases, like rating of
combustibles, the water content w may be more suitable.
The instrument can be configured to both of the values, please refer to chapter 6.
Moisture u (relating to oven-dry mass)
– recommended setting
The unit is %u (also common: % atro, weight percent)
mass
wet
:
mass of the sample (= total mass = mass
water
+ mass
dry
)
mass
water
: mass of the water contained in the sample
mass
dry
:
mass of the oven-dried sample after (water has been evaporated)
Example: 1 kg wet hay that contains 500 g water has a moisture u of 100%
Water content w (= moisture relating to wet total mass)
The unit is % w.
Example: 1 kg wet wood that contains 500 g water has a water content of 50%
m
oisture u[%] = ( (mass
wet
- mass
dry
) / mass
dry
) *100
or:
m
oisture u[%] = (mass
water
/ mass
dry
) *100
water content [%] = ( (mass
wet
- mass
dry
) / mass
wet
) *100
or:
water content [%] = (masse
water
/ mass
wet
) *100
