    3 Dots Cobalt Free Humidity Indicator Card

    Humidity indicator card is a product that detects relative humidity in sealed packaging, while cobalt-free halogen-free humidity card is one of the most advanced products, after the use of human skin process found to detect moisture is non-toxic and harmless

  • 3 Dots Cobalt Free and Halogen Free Humidity Indicator Card

    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.

    3 Dots Cobalt Dichloride Free Humidity Indicator Card

    Humidity indicator cards are used in sealed packaging of high-grade electronic components and instrumentation (e.g. integrated circuits, ICs, chips, etc.) that are sensitive to humidity. when the improvement of environmental requirements in the industry, environmentally humidity indicator cards without cobalt dichloride are produced.

    Cobalt dichloride-free humidity indicator cards are used to show relative humidity in enclosed spaces.  it cannot approach liquid water. Indicates that the colors within the dot vary with humidity, that the color changes in the dry and wet states of different products are easy to identify, and that the indicator values are stable and reusable.

    Cobalt-free humidity cards do not contain cobalt dichloride and meet environmental requirements.there are manufactured specifically for customers who meet cobalt-free requirements in EU regulations. Before drying is the brown state after moisture is sea blue. It is used to show the sealed space humidity status of the card, it detects whether the humidity in the sealed package is within the safe humidity range the card display percentage, the discoloration can be read out the sealed package is currently the humidity size. Cobalt-free humidity card is widely used in ICs, semiconductors, precision electronic components, precision optics and other high-end electronics, equipment due to the impact of moisture welding, component damage, and other hazards, to avoid electronic components by moisture erosion and damage, according to the IPC-JSTD-O33 moisture-proof standard most products will use moisture-proof packaging combination, and humidity display card is one of the materials of moisture-proof packaging combination.

    Cobalt-free halogen-free humidity indicator card, environmental humidity indicator card in order to meet the convenience, safety, reliability, and convenience of the detection of closed environment humidity at the same time, highlighting the advantages of non-polluting in the working environment, no harm to human health. The detection of ROHS standards, the inspection of hazardous substances stipulated by the national standard, and the updated third-party SGS test report all play a role in monitoring, inspecting, and publicizing the environmental protection of humidity cards. Products meet their health and safety requirements when exported to any country. Environmentally friendly humidity indicates that the point on the card will change from yellow to green.

    Most high-end electronics, instruments, and equipment, such as electronic components and precision optics, are highly susceptible to moisture, resulting in rust, reduced sensitivity, and even irreversible damage to products. Most products of finished and semi-finished products in the packaging phase will use a moisture-proof packaging combination to protect the product. The humidity indicator card is a simple, inexpensive material that quickly detects whether humidity is under control. When the sealed bag is opened, the data read by the color display on the humidity card can be used to monitor the humidity in the sealed package is within the specified humidity range. At the same time, it can indirectly reflect whether the desiccant in the sealed packaging plays a role in moisture absorption. Finally, the user can get the effectiveness of the desiccant or evaluate the packaging method
