Humidity Indicator Card (HIC) is a kind of visible card with several dots that can change the color from "Dry" to "Wet", each dot on the card indicates one specified relative humidity degree.
The dot color will change along with the RH degree from blue to pink (common cobalt-containing HIC) or brown to azure (cobalt-free HIC). It can help the users to know the inside humidity condition and decide whether the desiccant should be replaced or not.
It's so easy to monitor the interior humidity conditions of the package that can prevent the goods from moisture damage
The speed of the color change is adjustable
The commonly-used types are 5-10-60%, 30-40-50%, 10-60% and it's available to be customized.
The color change is reversible that the color will come back to the original one with the decrease of the humidity
