Water activity and moisture content meter
AQUALAB 3
Fast, predictive water activity and total moisture measurements that enable real-time control and better decisions across production environments.
Built for production, QA, and R&D teams
AQUALAB 3 uses chilled mirror dew point sensing and predictive AI to measure water activity and moisture content, helping food, pharmaceutical, and process manufacturers control moisture faster from formulation through finished product.

Predict, adjust, control
AQUALAB 3 delivers fast, accurate water activity measurements alongside total moisture content, enabling manufacturers to predict outcomes, adjust processes sooner, and maintain tighter control across diverse sample types.
One-minute insights
Predictive modeling delivers actionable water activity and moisture content data in as little as 60 seconds, reducing wait times compared to traditional methods—even for coated, high-fat, or complex products.
Trusted accuracy
Chilled mirror dew point technology delivers ±0.005 aw accuracy and up to 10× better moisture accuracy than the average moisture balance, supporting tighter specifications without increasing safety margins.
Proactive moisture control
Early indicators allow operators to adjust belt speed, temperature, or water content before problems occur, helping reduce failed batches, rework, and costly production interruptions.
Built for the line
AQUALAB instruments perform reliably in harsh production environments, delivering consistent, lab-quality measurements without requiring controlled laboratory conditions.
Compliance simplified
Secure data syncing, user management, and device connectivity help teams meet regulatory requirements and satisfy audits with minimal operational overhead.
Stackable by design
AQUALAB 3 features a compact, fully stackable design that saves valuable bench and line space, making it easy to deploy multiple instruments in crowded production and process control environments.
Ready out of the box
Each AQUALAB 3 ships with a calibrated sensor block, SKALA software, required accessories, and optional iPad—so teams can install quickly and begin generating reliable measurements immediately.
