Fig. 23. Error value in relation to the density of weighed sample

2. The test monitors changes in mass of a sample within the time of a few hours, if:

mass sample is possibly constant (minor changes). In such case it is assumed, that

considerable effect on the final mass measurement result is caused by changes of air

density, which in turn is strongly affected by pressure, temperature and humidity.

In order to make the measurements reliable, it is necessary to determine the density

of air in the weighing room and the density of weighed object.
