Water activity indicates the amount of unbound water (free water) in a material. It is an important factor in food preservation and quality control - for example for the shelf life of meat or other foods. This quality factor, also known as the aw value, depends on the water vapor pressure in the material, the current temperature and the water vapor pressure in the environment.

The new AW4 meter allows quick and easy measurement of water activity. The Aluminum cell cup in this design allows aW measurement for very small sample amounts. In addition, this design also allows easier sensor replacement.

*For larger sample size check out our AW1, AW2 and AW3 meters.

Many products can be measured with our AW meter, such as pharmaceuticals, food and meat products, butter, fruit mixtures, spices, granules, PVC, mushrooms, xylitol or seasoning.

The measuring device is a laboratory device and enables measurements in accordance with EN ISO 21807. With our aw value measuring instruments, the shelf life and quality can be secured and controlled.
