Example 3. Unable to determine stable heating condition by changing temperature setting
Suspected causes of this are high content of volatile oil (liquid) in sample or carbonization of sample
surface, due to its darkness in color.
However, it is possible to measure and evaluate moisture content of such samples by measuring under the
same conditions (sample quantity, heating temperature, measurement termination condition), with
previously set heating temperature and measurement termination condition (terminates measurement
when the moisture loss value per unit of time underruns certain conditions).
Meanwhile, carbonization of sample surface could be avoided by placing a glass fiber sheet on top of the
sample, which enables heating under high temperature, therefore shortening measurement time and
improving measurement accuracy.
Such samples include coffee beans and green tea.
