    Silica gel – indicator is a dry grain fine-pored silica gel, impregnated with solutions of salts of cobalt. Silica gel indicator is used to control the relative air humidity (environment) in a confined space: production, transportation and storage of various materials. As they absorb moisture and decrease the activity, the granules change their color from blue to pink.
