DUO: Water Activity + Moisture Content

AQUALAB 4TE DUO

The AQUALAB 4TE DUO uses product-specific calibration models to read water activity and moisture content simultaneously, giving you two readings from a single sample.

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 Series 4. SKALA uses the appropriate model when the technician identifies a sample.
