aWLife Water Activity Meter
The aWLife excels in speed and precision for measuring water activity (aW) thanks to its dew point sensor, which directly measures actual water activity instead of secondary parameters.
Since June 2026, it will feature the aWData21CFR software, fully compliant with FDA 21 CFR Part 11 and EU GMP Annex 11, alongside firmware upgrades like Fast Calibration and FAST Mode. These enable calibration in approximately 2 minutes and analysis in approximately 40 seconds, ensuring compliance with ISO18787, USP 1112, and AOAC 978.18 and positioning it as one of the fastest and most accurate aW meters available.
The intuitive touchscreen and advanced calibration modes allow efficient measurements and optimized analysis, even with varying aW values. Data export is flexible, and the chamber’s smart design simplifies contamination detection and cleaning.
