We get repeated queries about calibration of our DuNouy Ring Tensiometers. That makes me think that calibrating procedures to insure accurate surface tension measurment needs some clarification.

Moisture Content - Water Activity – Are They the Same Thing?
Posted by Art Gatenby on Mar 6, 2012 4:19:00 PM
The other day, I woke up with a lingering quandary: Are the concepts of
Moisture Content and Water Activity the same thing?
As usual, I’ve decided to take on the task of clarifying the difference. I hope I pull it off.
From the perspective of someone who supplies instruments that measure moisture content, water activity has not been a primary consideration. However, I believe that comparison and contrast of these important concepts will be useful.
