Precision in Every Dot: Managing Humidity using Humidity Indicator Cards

Humidity Indicator Cards infused with a cobalt chloride solution change color to indicate changes in relative humidity. While they are not exact, they do show the maximum humidity in a container. For instance, if all of the dots on a 10%-60% card are unaffected, the humidity is less than 10%. A changing dot, such as 40% turning pink, indicates that the RH is in that range. To maintain proper humidity levels for moisture-sensitive products, quick action is required, either by relocating things or changing desiccant. Trust Humidity Indicator Cards for accurate humidity readings and moisture management in your storage containers.

Key Features:

  • Indicate Humidity conditions in various types of packaging
  • Allow instant visual verification of product integrity
  • Often used in conjunction with a desiccant
  • Approved for MIL-l-8835
  • Low Cost
  • Spots turn from Blue to Pink to indicate humidity levels

How To Use It?

It is simple to use Humidity Indicator Cards. Take the following steps:

  1. Placement: Insert the Humidity Indicator Card into the storage container with the items that need to be protected.
  2. Observation: Keep track of how the color of the dots changes over time.
  3. Interpretation: If all of the dots remain unaltered, the humidity is lower than the minimum specified threshold. A shifting dot, such as 40% turning pink, shows that the humidity level is within that range.
  4. Action: Take immediate action if the humidity level surpasses permissible values. Consider moving items or changing desiccants to maintain proper humidity levels.
  5. Checks on a regular basis: Check the Humidity Indicator Card on a regular basis to ensure continuous protection.

You can simply regulate and maintain the ideal humidity levels for your stored items by utilizing Humidity Indicator Cards, assuring their durability and quality.
