METHOD OF CONTROLLING AND MONITORING HUMIDITY IN HERMETICALLY SEALED CONTAINERS FOR STORING HYGROSCOPIC MATERIALS Russian patent published in 2013 - IPC G05D22/00 

FIELD: physics.

SUBSTANCE: dynamic measurement of change in humidity parameters is carried out by placing samples of hygroscopic materials and a weighed portion of a moisture absorber into a hermetically sealed container, and a subsequent series of opening the hermetically sealed container and inspection of humidity parameters in the hermetically sealed container is carried out in combination with calculation and replacement of another moisture absorber at the end of the storage period of the container of about 1-5 years.

EFFECT: maintaining stable equilibrium humidity in hermetically sealed containers for a long period of time, having rigid constraints on weight and size, the need for periodic process opening, in which hydroscopic materials are stored for a long period of time, said materials releasing a considerable amount of moisture, increasing the storage period of the hermetically sealed container to 18-20 years, high reliability and accuracy of maintaining equilibrium humidity in the hermetically sealed container.
