Industries
for a wide range of industries where controlling water activity and water content is critical
What's the Difference?
Water Activity Meter
Measures: How much water is free to act?
Counts only the free water, the part mold and bacteria can use.
Measure water activity if you need to:
- Predict mold and bacteria growth
- Set and prove shelf life
- Prevent staling, clumping and texture loss
- Stop moisture moving between ingredients
Moisture Analyzer
Measures: How much water is there?
Counts all the water in a sample, by weight.
Measure moisture if you need to:
- Hit recipe and product specifications
- Know when drying or baking is done
- Protect yield (don’t sell water by weight)
- Support nutrition labels and standards
