Humidity Indicator Card (HIC)

Humidity Indicator Card is a convenient and cheap safe way to detect the humidity of the environment. The user can quickly judge the humidity and the effect of desiccant in the product package by the color on the card. If the humidity in the package exceeds or is equal to this value, the corresponding point on the card will change from a dry color to a hygroscopic color, so that the effect of the desiccant can be easily known.
A necessary item for packing some products which is very sensitieve to humidity and the basic technology is using color change of spots according to the relative humidity.


What are they?

Humidity Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Available in numerous configurations, cards indicate relative humidities as low as 5 percent and as high as 95 percent, depending on the application and need.

Why use them?

High relative humidity levels can cause irreparable damage to sensitive equipment, supplies, products and cargo. While many shippers and manufacturers might take the proper steps to protect their products from moisture damage, such as using desiccants,it is sometimes difficult to know how effective those steps are. Some products, such as electronic goods, often show no visual sign of moisture damage, while desiccants may reach their absorption capacity before users realize they need to be replaced.
Humidity indicator cards help provide visual proof of the relative humidity level within a given environment. If the card indicates high levels of humidity, users know to replace their desiccant bags and check their products for possible damage.
