Product Description
Humidity Indicator Card (HIC)
Humidity Indicating Cards are the most accurate cards available in the market today. They are often used in conjunction with a desiccant and a moisture barrier bag when shipping electronic components.
To provide a simple, reliable, visual indication of the relative humidity within a sealed package or any given environment. 

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.
There are two main types of humidity indicator cards: reversible and irreversible. Reversible humidity indicator cards work much like a thermometer, fluctuating to indicate the current relative humidity level. Maximum, or irreversible cards are designed to indicate the highest relative humidity level to which goods have been exposed.
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.

Available configurations 

HICs are available in many configurations and can be customized for any number of applications. It meets military specifications (Mil-I-8835 and Mil-Std-2073- 1D Method 50) and JEDEC standards (J-STD-033A and anticipated revision J-STD-033B). One-spot, three-spot, four-spot and six-spot cards are currently available, in a range of customizable humidity levels.

1.Usage Requirements
Humidity indicator spots change from blue (dry) to pink (humid) as relative humidity changes.
Current relative humidity is indicated by a lavender color.
Indicator spots will change within eight hours of being exposed to a change in relative humidity. 
Humidity indicator spots are reversible. Pink spots will change back to blue when the volume of air is dried. Pink or lavender spots can be returned to blue by placing them in a sealed container with one unit (33 grams) of desiccant for 48 hours.

The highest humidity indicator spot should be blue before the card is put to use. 
The humidity indicator card will be at its most accurate when used at a temperature of 73°F (23°C).
Avoid contact with indicator spots. Wash any irritated areas with clean water.
2.Storage and Handling
 When storing, keep indicators in their original container, sealed with a desiccant if possible.
 Replace desiccant after container is opened three times.
 Store in a cool, dry area.
 Keep indicators away from water or steam.
 Keep away from ammonia gases, which will render the indicators useless. 
1.Usage Requirements 
Each level of humidity is represented by a blue crystal.
The blue crystal will dissolve into an unmistakable large blue spot when its indicated humidity level has been reached for more than 24 hours.
2.Storage and Handling 
When storing, keep indicators in their original container.
Do not open individual bags until ready for use.
Store in a cool, dry area.
