AW Tester

Water activity (aw) is an important parameter in various industries, including the food industry, pharmaceuticals, cosmetics, and more. Measuring water activity makes it possible to determine the availability of water in a material, which in turn affects the stability, quality, and shelf life of products. Water activity, often abbreviated as aw, is a measure of the availability of free water in a material. It is measured on a scale of 0 (no water activity) to 1 (pure water). This measurement is crucial because it provides information about how much water in a product is available for microbial activity, enzymatic reactions, and chemical changes. aw meters use various technologies, including capacitance measurement, infrared sensors, and electromagnetic fields, to determine water activity. These instruments enable precise measurements and help monitor the quality of products during storage and shelf life. In the food industry, controlling water activity is critical to prevent the growth of microorganisms and ensure product shelf life. aw measurements are used in the production of bread, meat products, confectionery and other food products.
