The hygiene/food testing device is a mobile measuring device for water activity. Water activity indicates the amount of water that is biologically available to microorganisms such as bacteria, mold or similar. Each type of microorganism has a minimum value for water activity below which growth is no longer possible. The higher the aw value of a food, the more perishable it is. Bacteria usually require a water activity of over 0.98, but significantly lower water activities of up to 0.6 can also be tolerated by extremely halophilic bacteria, for example.
