Water activity is the critical parameter for food quality and safety of various products from foods to pharmaceuticals. Water activity measures the amount of “free” water in a product, the water available for microbial growth and chemical reactions, making it possible to predict product stability, shelf life, and safety.

AW-1 is a compact, easy to use, and reasonably priced yet high-precision water activity analyzer. Despite its small size, AW-1 delivers high-precision and measurement accuracy of ±0.01 aw at an ambient temperature ±0.2 ℃.
