For use with Water Activity Meter to verify accuracy.
Why Water Activity Matters
- Extends shelf life
- Improves product safety
- Supports regulatory compliance
- Optimizes production
- Enables stable, high-quality formulations
It is recommended to perform water activity calibration if the measurement result of the saturated salt under
the same conditions as sample measurement deviates by more than ±0.02* from the reference value.
Salts are reusable.
Do not pierce waterproof breathable film.
Recommend to replace after one year.
To use: Open the lid and set it on the sensor to complete preparation.
Please follow the testing standards based upon your sample product.
