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.It meets military specifications (Mil-I-8835 and Mil-Std-2073- 1D Method 50) and JEDEC standards (J-STD-033C ). One-spot, three-spot, four-spot and six-spot cards are currently available, in a range of customizable humidity levels.

Purpose

To provide a simple, reliable, visual indication of the relative humidity within a sealed package or any given environment.

REVERSIBLE CARDS
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 the HIC 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.
