The AW3 Humimeter is simply the most accurate Aw meter due to a combination of its unique features: 

1. All Humimeter Aw models gently circulate the air in the chamber to prevent stratification + equalize the temperature

2. The AW3 utilizes a thermal barrier to further stabilize the temperature. Even 2C variances that are typical in an average room over the typical 2-5 min Aw cycle will increase errors significantly.  *See Aw Paper

3. We Utilize a grinder to finely grind products before testing. The finer a product is ground, The greater the surface area to enhance moisture equalization within the Aw Chamber. Larger Chunks will not equilibrate within 5 minutes.

- Combining Finely Ground Samples, A Thermal Barrier to control temperatures, and air circulation makes this the only Aw meter to give "REAL" Aw readings typically in under 5 minutes.
