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 application 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
moisture u[%] = ( (mass
or: moisture u[%] = (mass
The unit is %u (also common: % atro, weight percent)
mass : mass of the sample (= total mass = mass
wet
mass : mass of the water contained in the sample
water
mass : mass of the oven-dried sample after (water has been evaporated)
dry
Example: 1 kg wet hay that contains 500 g water has a moisture u of 100%
