AQUALAB 3
Figure71 List of compeleted total moisture readings
The AQUALAB3 reports the reading when equilibrium is reached; for many products,
equilibrium will occur in 5 min or less. However, some types of products may take longer,
such as products with
• a moisture barrier (e.g., whole seeds and nuts),
• a high fat content (e.g., peanut butter),
• extremely low water activity, or
• multiple components (e.g., cakes with filling, cheese and crackers, cereal with fruit).
Contact Customer Support to help determine if the product requires longer read times and if
any actions may shorten the read time.
2.5.3 ONEMINUTE WATER ACTIVITY READING MODE
The One-Minute Water Activity Mode feature enables a reading to complete after 1 min. This
feature can be added when a monthly subscription is activated. Figure59 shows a lightning
bolt next to a reading that was taken in one-minute water activity mode. Learn more about
SKALA subscription plans and One-Minute Water Activity Reading Mode at metergroup.com/

2.5.4 SETTING UP ISOTHERMDETERMINED MOISTURE CONTENT
The AQUALAB 3 calculates moisture content values based on water activity readings using
a method known as isotherm-determined moisture content. Isotherm-determined moisture
content relies on models stored in the SKALA isotherm library or on a custom isotherm
model provided by METER Food Lab Services.
