equilibrium moisture content

[‚ē·kwə′lib·rē·əm ′mȯis·chər ‚kän·tent]
(physical chemistry)
The moisture content in a hydroscopic material that is being dried by contact with air at constant temperature and humidity when a definite, fixed (equilibrium) moisture content in the solid is reached.

equilibrium moisture content

The moisture content of a material that is stabilized at a given humidity and temperature.
