Dewpoint Water Activity Meter (AquaLab PRE) | Lee Hung Scientific Pte Ltd


  • Features

The AQUALAB PRE is a robust, entry-level water activity meter with stripped down form, not limited function. It uses the same industry-standard primary aw method you find in the top-of-the-line AQUALAB Series 4TE. The PRE may look basic, but that’s because all the good stuff is inside.

  • Uses the dewpoint method—a primary measurement of water activity that eliminates the need for lengthy sensory calibration. Just a quick verification check and you’re good to go.
  • Measure over the whole range of water activities, 0.05 to 1.00 aw.
  • Water activity is temperature dependent; measuring at the same temperature every time assures consistency in your readings.
  • Solid repeatability - the PRE holds the sample at 25 °C
