Water Activity

Foods and Fine Chemicals

Water activity is a measure of the thermodynamic activity of a material in the presence of water vapour and is commonly used in the food industry. The DVS is an ideal way to measure the water activity of solid materials across a wide range of temperatures and can work with very small sample sizes.
