Product Description 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 meters.
Pre uses the dew point method_a primary measurement of water activity. That eliminates the need for lengthy sensor calibration. Just a quick verification check and you're good to go.

No need to sacrifice accuracy for speed. Primary dew point measurement allows Pre to deliver top-accuracy readings in 5 minutes or less. Water activity is temperature dependent; measuring at the same temperature every time assures consistency in your readings. Pre holds the sample at 25 °C so temperature fluctuations won't affect your readings. Pre's dew point method and temperature-stable features mean good agreement between the Pre and the Series 4. Its basic 0.01 aw accuracy enables many of our customers to add water activity testing at the line, loading dock, or offsite facility.
