Water activity
Good and safe products are important. You can monitor the quality
and shelf life of your product perfectly by measuring water activity.
Water activity influenses the microbiological and chemical stability
of perishable products. Control of water activity has a huge impact
on the shelf life and quality of products. With Aw-equipment of
Rotronic you can measure water activity very accurate. ACIN instrumenten
can advise you when purchasing and using water activity instruments.
What is water activity?
Water activity (Aw) measurement is most commonly used in the food
and pharmaceutical industry, where it's used to determine shelf
life and quality. The Aw of a product is measured in a closed space
at a constant temperature. Measuring water activity with equipment
of Rotronic means measuring the relative humidity of the air around
the product within a scale of 0..1. This is a measure for microbiological,
chemical and enzymatic stability of perishable products such as
food, seeds and medicines.
Rotronic Aw-equipment
The ROTRONIC range of water activity instruments uses the latest
digital technology to introduce new levels of measurement performance,
application flexibility and new features. Multiple probe inputs,
PC based data handling, intrument networking, software based calibration,
and interchangeable measurement stations are just some of the features.
