PCE AW tester PCE-WAM 10

The AW tester is a mobile measuring device for water activity. The water activity indicates the amount of water that is biologically available for microorganisms such as bacteria, moulds 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 activity of up to 0.6 can also be tolerated by extremely halophilic bacteria, for example.

The AW tester has a measuring range of 0.01 aw ... 1 aw with a high accuracy of ±0.03 aw. The measuring attachment is magnetic so that the sample can be measured safely and protected from light. The AW tester comes with 3 sample dishes, which can be used to quickly test the shelf life of many foods. In addition, 2 AAA batteries 1.5V to operate the AW tester. The AW tester is used in the food industry, for analysing water activity in laboratories, in seed storage and other areas.
