Laboratory Analyzer for water activity measurement

HYGROLAB - Laboratory device for water activity measurements

ATTENTION: The FDA 21 CFR Part 11 conformity will be available later with the necessary validation documents (IQ/OQ).

The Rotronic HygroLab is an innovative high-end laboratory analyzer for water activity measurements with up to four measurement probe inputs.
