A humidity indicator card (HIC) is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded.
This item is an inexpensive way to quantify relative humidity levels inside sealed packaging.

The most commonhumidity indicator cards change color from blue (less than indicated RH level) to pink (greater than indicated RH level).
