Water activity meter, indicates the free water content when food is stable, measures the possibility of microbial proliferation.
Food formulators use water activity to predict how much moisture migration will affect their product, so that to choose suitable package and storage method to reduce the usage of antiseptics.
Features:
1.The measured object is unlimited, liquid solids and powder etc
2.Printer output as standard accessory
3.Chemical resistant. (only for BWA-6)
