Humidity Indicator Card

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 has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base and special plastic films

Humidity indicators are an inexpensive way to indicate or quantify relative humidity levels inside sealed packaging. They are available in many configurations and used in many applications, especially military and semiconductor.

Color change: Blue-Pink

Construction:

Humidity Indicator Cards are constructed of a moisture-sensitive blotting paper.

Application:

PCB packing, IC packing, semiconductor packing, SMD LED packing and so on.
Designed specifically for the electronics industry. Ideal for use with other components of the "Dry Pack packaging concept.

Storage:

- Keep sealed and dry.

- Keep away from direct sunlight
