Moisture activity meter / water activity meter / water activity meter

Water Activity mainly reflects the state of water in the state of material balance. A variety of microbial activities and various chemical and biochemical reactions have a certain AW threshold, so AW affects the nutrition, flavor, color, texture, rheological properties and microbial growth of biological products. The AW value can be determined to determine the shelf life of the product, and to select reasonable storage conditions and packaging materials.
