Water Activity Analyzer Food Safety – 0.05-1.000aw-±0.01aw

Introduction: Precision Water Activity Control for Food and Research Laboratories

Water Activity (aw) measurement is a critical parameter for laboratories involved in food research, quality assurance, and safety compliance. Unlike moisture content, water activity directly influences microbial growth, chemical stability, texture, flavor, and shelf life. The Aqualab Pre Water Activity Meter is engineered to deliver fast, repeatable, and highly accurate results, enabling laboratories to make confident decisions based on scientifically reliable data.

For laboratories seeking consistent measurements, reduced testing time, and dependable compliance with international standards, the Aqualab Pre Water Activity Meter provides a proven solution grounded in advanced sensing technology.

Understanding Why Water Activity Matters

Water activity represents the energy status of water within a product, indicating how tightly water molecules are bound. This parameter directly affects microbial stability, enzymatic reactions, and chemical changes. The Aqualab Pre Water Activity Meter allows laboratories to precisely monitor these narrow ranges where product quality can rapidly change.

By using the Aqualab Pre Water Activity Meter, laboratories gain insight into product behavior rather than relying on indirect moisture measurements.

Core Technology: Chilled Mirror Dew Point Measurement

The Aqualab Pre Water Activity Meter utilizes chilled mirror dew point technology, recognized as one of the most accurate methods for water activity determination.

Measurement process includes:

• Sample placement in a sealed cup against a sensor block
• Dew point sensor measuring headspace dew point temperature
• Infrared thermometer measuring true sample temperature
• Integrated fan accelerating equilibrium and stabilizing boundary layers

Once equilibrium is achieved, the Aqualab Pre Water Activity Meter calculates water activity from relative humidity with exceptional repeatability.
