Repeatable measurements, solid support
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 things are inside.
No calibration. Pre 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.
Real water activity--FAST. Primary measurement allows Pre enjoy a distinctive advantage in speed. Pre delivers top-accuracy readings in five minutes or less—no need to sacrifice accuracy for speed.
Solid repeatability. Pre holds the sample at 25°C so temperature fluctuations won’t affect your readings. Water activity is temperature dependent; measuring at the same temperature every time assures consistency in your readings.
Reliable accuracy. Pre’s dewpoint method and temperature-stable features mean good agreement between the Pre and the Series 4. Its basic 0.01 awaccuracy enables many of our customers to add water activity testing at the line, loading dock, or offsite facility.
Dependable support. Pre includes Decagon’s trademark free technical support—food scientists and instrument specialists just a phone call away.
Full range. Pre lets you measure over the whole range of water activities, 0 to 1.0 aw.
Measure Samples with Volatiles. Unlike AquaLab Lite, Pre can use a dewpoint or a capacitance sensor, so samples containing alcohols, propylene glycol, and other volatiles can be read.
Connect to a Computer. Pre can be connected to a laptop or desktop computer to download and store readings.
