    Explain:

    Cobalt free humidity indicator card, humidity indicator card, humidity card, Guangdong cobalt free humidity indicator card, Guangdong Guangdong humidity humidity indicator card, card, Yongxing cobalt free humidity indicator card, Yongxing Yongxing humidity humidity indicator card, card, the cobalt free humidity indicator card, the humidity indicator card, the EU does not contain the humidity card. Cobalt chloride humidity indicator card (humidity card) is used to indicate the relative humidity size product packaging container. Relative humidity RH refers to the saturation percentage of air in a certain volume of air. The relative humidity RH<50% and relative humidity RH can be controlled by desiccant when the goods do not mildew during storage and transportation, and the desiccant will lose its function when water absorption reaches a certain degree. The humidity indicator card can conveniently detect the relative humidity in the sealed package. When the indicator point becomes purple (before blue and pink), the indicator point is the current ambient humidity. The humidity indicator card is a convenient and inexpensive method for detecting the humidity in the environment. If the humidity in the package has reached or has reached the humidity value, the point on the card will change from blue to pink. The use of the company's humidity indicator card products, you can make your products, especially some precision products without danger of moisture.

    The humidity indicator card is a convenient and inexpensive method for detecting the humidity of the environment. The user can quickly determine the humidity in the package and the effect of the desiccant through the color on the card. If the humidity in the package exceeds or equal to the moisture value, the corresponding point on the card will change from dry color to moisture absorption color, so the use effect of the desiccant can be easily understood.

    In 2004 the EU environmental regulations (2004/73/EC) has been listed as the two types of cobalt chloride on cobalt containing carcinogenic substances, now kind of humidity indicator cards to prohibit the use of materials, all products exported to EU countries must comply with the regulations. Therefore, a large number of humidity indicator cards (from blue to pink), the main component of cobalt chloride, will soon be prohibited use. For example, the SS-00259 8 version of SONY prohibits the use of cobalt chloride humidity indicator cards and other products.

    In order to adapt to the relevant laws and regulations and environmental protection development requirements, our company set up a special humidity card division, and has developed a new generation of environmental humidity indicator cards (type I, type II, type III). The production process and the indicator card big upgrade, daily output of more than 60000, the products meet the EU RoHS directive (excluding SGS), have been detected by means of CTI, and indicates the obvious color change, excellent workmanship, easy to use.

    Production standard:

    * 2004/73/EC (EU environmental regulations)

    * GJB2494-95 (People's Republic of China military standard)

    * MIL-I-8835A (US military packaging standard)

    * JEDEC (electronic component industry association standards)

    Applicable scope:

    * electronic components packaging, optical equipment, sensitive components, all kinds of vacuum packaging, IC / integrated circuit board, etc.

    Instructions:

    1. when the humidity of the environment is reached or the indication value of the indicator point on the humidity indicator card, the indicator will change from dry color to moisture absorption color.

    2. when the humidity of the environment decreases, the color of the indicator card will change from the moisture color to the dry color.

    3. when the color of the indicator point becomes the specified color, the value in this point is the humidity value of the current environment.
