Description
The Water Activity mainly reflects the amount of free water in the state of food balance, the stability of food and the possibility of microbial reproduction, and the chemical, enzyme and physical changes that can cause the change of food quality.
This meter is calibrated by factory, usersdo not need to calibrate again, just input samples and testwhich is very simple.

If you want to verify the accurate, you can make the standard salt solution by the following steps: 1. 100g pure NaCl, add into 200g hot distilled water, stir it. Then wait till to room temperature. 2. Keep the solution into a brown bottle for one week in room temperature. 3. In room temperature 25��C (77��F), make sure the meter, solution, room temperature all same temperature. The solution AW value should be 0.73~0.77
