WATER ACTIVITY


Rotronic is a world leader in water activity and water activity measurement devices. In the food, paper and pharmaceutical industries they are used as an alternative to moisture meters and moisture measurement. Water activity measurement also offer advantages in terms of speed of response, less complex procedures and a non-destructive technique. Moisture meters and moisture measurement can be complex, expensive and are difficult to calibrate with traceability – a key requirement in meeting Quality Control requirements.

Rotronic moisture meters offer a reliable and accurate way to establish water content in products, processes or environments. Our moisture meters use water activity measurement as the principle to determine humidity levels – a simple and straightforward technique that will provide you with moisture measurements that you can trust. Moisture and humidity are inter related by Sorption Isotherms.

In process control, moisture measurement is used to control drying processes. Many of our clients use our moisture instruments to establish storage and shelf life for finished products like paper, drugs and processed food and to determine appropriate packaging.

The Rotronic moisture meter range includes:

  • The HygroLab range of benchtop displays for water activity solutions
  • The AW-DIO moisture measurement station for use with HygroLab or HygroPalm handheld displays
  • The AW-Quick PC based moisture meter software
  • HygroPalm AW for portable moisture measurement
  • BF plate probe for online moisture measurement on moving materials such as paper, textiles and powders
  • HygroFlex transmitters for dryer monitoring
