Introduction Water activity, aw, is most frequently measured in bacteriological control and for stability purposes. During 1997, a portable instrument for aw measurements was acquired by EminTech. The results obtained from the instrument never felt convincing. In order to understand how to make aw measurements and also to get information about which instrument to acquire, three portable instruments were studied during 2004. It was realised that none of them was as reliable as required by EminTech. During 2005, three desktop instruments were studied. The price tag of these instruments was higher than that of the portable instruments, but so was also their performance. |
