Water activity meter, indicating the free moisture content of food when stable, measuring the potential for microbial growth. Food formulators use water activity to predict how much moisture migration will impact their products, thus selecting appropriate packaging and storage methods to reduce the use of preservatives.
Measurements can be performed on liquids, solids, powders, etc.
Readings and sensors are combined.
Quick test, five minutes to detect water activity
The samples' temperature, water activity, and ease of reading were all shown together.
To communicate with the PC, use the "USB data line output."
