Water Activity Meter WA-60A
The WA-60A Water Activity Meter is designed for measuring water activity in foods. This portable device provides precise measurements anytime, anywhere, making it the ideal choice for food quality control and shelf life assessment.
Understanding Water Activity
Water activity primarily reflects the amount of free water in food at equilibrium state. This measurement indicates food stability, microbial growth potential, and chemical, enzymatic, and physical changes that affect food quality. It is commonly used to assess microbial resistance to dryness. By measuring water activity and selecting appropriate packaging and storage methods, manufacturers can reduce preservative usage and accurately determine the shelf life of food, grains, fruits, and vegetables.
