Used in a variety of dry packaging applications, this card monitors humidity levels across the widest range. Humidity Indicator Cards are printed with moisture sensitive spots which respond to various levels of humidity with a visible color change from blue to pink. HIC's are placed inside vacuum sealed (dry packed) moisture barrier bags. When the bag is opened, the card can be examined for proper dryness inside the bag.
