3 Dots Cobalt Free and Halogen Free Humidity Indicator Card
Cobalt-free halogen-free humidity indicator card (COBALT FREE HALOGEN FREE) is a simple and inexpensive safe way to detect ambient humidity, users can immediately determine the color on the card in the product packaging humidity and desiccant effect. If the humidity in the package exceeds or equals the humidity value, the corresponding point on the card will change from a dry color to a moisture-absorbing color, which makes it easy to know the effect of the desiccant.

Electronic component packaging, optical equipment, sensitive components: All kinds of vacuum packaging, IC/integrated/circuit board, semiconductor packaging testing, LED packaging, IC packaging, computer information equipment industry, bio-chip, and other industries moisture-proof de-humidification.
Compliance with standards：2004/73/EC (EU Environmental Regulations): GJB2494-95 (Military Standards of the People’s Republic of China) – MIL-I-8835A (U.S. Military Packaging Standards): IPC/JEDEC J-STD-033B (Electronic Components Industry Federation Standard)
1. When the humidity of the environment reaches or exceeds the value of the indicator point on the humidity indicator card, the color of the indicator point of the humidity card changes from dry color to moisture absorption color.
2. When the humidity of the environment decreases or when the environment is dry, the color of the point indicating the card changes from the absorbent color back to the dry color.
3. When the color of the indicator point changes to the specified color, the value in that point is the humidity value of the current environment.
Humidity indicates that the card closure needs to stored in the packaging tin cans, and at the same time put a certain amount of desiccant, so that the tank remains dry, packaging open three times after please replace the desiccant, to avoid the failure of the humidity card, humidity card can only be stored in a dry, cool environment. Do not be exposed to direct sunlight and flooding.
