Abstract
A moisture sensing unit (30, FIG. 1 or 58, FIG. 4) is included within a hermetically sealed package. A localized external portion of the package in close proximity to the unit is cooled while the temperature and the alternating-current capacitance and/or conductance characteristic of the unit are measured. The measured characteristic exhibits a sharp increase at the temperature corresponding to the dew point of the atmosphere within the package. In turn, the dew point temperature is a direct indicator of the moisture content of the package.
