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.
