Why different models?

Because every sample has its own characteristics in terms of ingredients, texture, color and taste and thereby influences the free water and finally the water activity in a different way. This factor plus the temperature influence defines the measurement time and accuracy of the same. Stable measurement conditions are finally the key to a successful quality control!
