Environmental Cobalt Free Brown to Green Humidity Indicator Card

  • The Humidity Indicator Card (HIC) is a cost-effective and reliable tool for monitoring environmental humidity levels. By observing the color change on the card, we can easily determine the humidity inside the packaging. When the humidity reaches or exceeds a specific value, the dot on the card changes color from DRY to WET, providing a clear indication of the effectiveness of the desiccant.
  • The HIC is made of 0.4mm thick blotting paper, ensuring its durability and functionality. It can be customized to display humidity levels of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90%. Additionally, the HIC meets the standards set by JEDEC J-STD-033 and GJB2494-95, ensuring its reliability and compatibility.

Product Description

  Humidity Indicator Cards (HICs) are compact paper devices created to monitor the levels of relative humidity. With various options available, these cards can detect relative humidity ranging from as low as 5 percent to as high as 95 percent, catering to different applications and requirements.

  There are two primary types of HICs: reversible and irreversible. Reversible HICs function similarly to a thermometer, displaying fluctuations to indicate the present relative humidity level. On the other hand, irreversible HICs are specifically designed to record the maximum relative humidity level that goods have been exposed to, serving as a permanent indicator.

 HICs



APPLICATIONS

    Moisture can have a detrimental impact on high-end electronic and instrument equipment, such as electronic components and precision optical components. It can lead to product corrosion, reduced sensitivity, and even irreversible damage. To safeguard against moisture-related issues, manufacturers often employ moisture-proof packaging methods during the final and semi-finished product stages.

    One effective tool for monitoring and maintaining optimal humidity levels is the humidity display card. This card serves as a convenient and cost-effective solution for detecting whether the humidity inside the sealed packaging remains within the desired range. By simply opening the sealing bag and observing the color display on the humidity card, one can assess whether the humidity falls within the specified limits. Furthermore, it indirectly indicates the effectiveness of the desiccant inside the sealed packaging in absorbing moisture.
