DUO: Water Activity + Moisture Content
Get two measurements from one sample—simultaneously
AQUALAB 4TE DUO
All AQUALAB instruments now come with DUO functionality so you can measure water activity and get moisture content simultaneously from a single sample. To use the DUO function, you need a product-specific calibration model for each of the products you want to measure.
Best products
Most products with less than 40% moisture (by weight) will work using DUO calibration models. Products with moistures above 40% usually have such uniformly high water activity values that other moisture analyzers are a better fit.
High precision and repeatability
Below 40%, moisture changes affect water activity readings more strongly, yielding high precision and repeatability.
SKALA adds DUO models to any AQUALAB
Add product-specific calibration models to any SKALA-connected water activity instrument. SKALA uses the appropriate model when the technician identifies a sample.
