Water Activity (aw) is the relative humidity which is reached at equilibrium in a sealed container in which a hygroscopic product has been placed, but expressed on a scale of 0…1. Water Activity measurement is most commonly used in the food industry, where it is used to determine shelf life and quality.

Equilibrium Relative Humidity (ERH) is the value of relative humidity into which a Hygroscopic product can be placed where no net exchange of moisture between the product and the surrounding environment can take place. It is expressed on a scale of 0…100%. ERH is typically used in the paper and pharmaceutical industries, but can be applied to almost any product that is sensitive to moisture, or where the presence of moisture can effect product handling.

Water Activity measurement offers a non-destructive, easy-to-use measurement in a wide range of convenient configurations for both laboratory and on-site use.
