humidity indicator card (HIC)

A card on which a moisture-sensitive chemical is printed such that it will undergo a significant, perceptible change in color (hue), typically from blue (dry) to pink (wet) when the indicated relative humidity is exceeded.

NOTE The HIC is packed inside the moisture-sensitive bag, along with the desiccant, to aid in determining the level of moisture to which the moisture-sensitive devices have been subjected.
