Humidity Indicator Cards
 

• 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.
