METER AQUALAB 3 (AQ3), Benchtop Water Activity Meter

ONE MINUTE WATER ACTIVITY

Water activity + moisture content in one minute

The speed challenge

Normally, measuring water activity takes a significant amount of time. The sample must come to equilibrium with the air in the headspace above the sample before a reading can be taken. Depending on the sample, that can take 2-5 minutes—even longer for coated products and products high in fat. There hasn’t been a way around “equilibrium time” or “dwell time.”  Until now.

Fast answers, no waiting

The new AQUALAB 3 breaks the speed barrier. Using SKALA-powered predictive AI, it delivers both water activity and moisture content readings on a single sample in one minute.

Clear shipments quickly

AQUALAB 3 lets you know within one minute whether the batch will pass or fail.  Quickly test as many samples as you need to establish a robust testing protocol and accurately predict in-package water activity. Don’t wait for answers—clear shipments quickly and avoid logistical snarls.

Avoid rework and scrapped batches

Make fast decisions at the line to address issues before your process goes out of control. Get “outside operating limits” indicators within 60 seconds and use the predicted final values to adjust belt speed, oven temperatures, water content in dough, and other parameters before they result in rework or scrap. Fast water activity measurements offer the most precise way to monitor and control moisture at the line.

Speed changes everything

One minute water activity offers options you’ve never had before for robust and rapid pass/fail determination, tighter process control capability, and rock-solid indicators to clear shipments on time.
