Water Activity Meter




Description :

Introduction:

Water activity or aw , indicates the free water content when food is stable, measures the possibility of microbial proliferation.

Food formulators use water activity to predict how much moisture migration will affect their product, so that to choose suitable package and storage method to reduce the usage of antiseptics.
 

Features:

  1. DWA-300 water activity is a single-point measurement equipment, adopting high precision sensor
  2. Professional design ensures stable and reliable performance;
