  • Fast: water activity meter gets readings in 5 minutes or less
  • Accurate: ±0.003 aw
  • Verifiable with independent salt standards
  • Repeatable: different users, different locations, same result
  • Portable: weighs just 7 pounds
  • Easy to use: water activity meter yields precise measurements with minimal training
  • Secure: offers administrative control over calibration and sample data
  • Proven: used by 80 of the top 100 food companies

How it Works

Put a 7.5 ml product sample in a disposable cup, place in the water activity meter, seal the sample chamber lid over the sample and wait for vapour equilibrium.

An infrared beam focused on a tiny mirror determines the precise dewpoint temperature of the sample. That dewpoint temperature is then translated into water activity.

Secure Data

The AquaLab Water Activity Meter 4TE stores time, date and user information with every measurement and calibration and can store up to 10,000 secure data points.

Administrative functions can be set to control access to data. Designate up to 25 unique users and passwords. Use the USB or RS-232 serial data port to download or print data for statistical analysis and to maintain compliance records and archives.
