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.
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.
