Humidity Indicator Card

Humidity indicator cards are moisture indicators that detect and undergo colour changes depending on the humidity level in the surrounding environment.

Moisture Monitoring Solution

Humidity cards monitor and control humidity levels to ensure product quality, prevent damage or corrosion and maintain optimal conditions for sensitive products.

Moisture control cards visually indicate if humidity exceeds safe thresholds, enabling timely interventions to mitigate potential risks and maintain desired humidity levels in different environments.

Indicator cards are affordable, compact, and easily readable. We supply a wide range of humidity monitoring cards approved to comply with the JEDEC Standards.

Available in Different Humidity Levels

By using humidity indicator cards, users can easily monitor and verify if the humidity conditions are within the specified range, allowing for timely interventions or adjustments to maintain the appropriate moisture levels. HICs are often used in conjunction with desiccants and moisture barrier bags for enhanced moisture control.

Cobalt Dichloride Free

Cobalt dichloride-free humidity indicator cards (blue humidity indicators) are impregnated with a carefully mixed cobalt chloride solution. This solution allows the card to detect and change colour from blue to pink once a specific relative humidity level has been reached.

Available in RH levels ranging from 5% to 60%.

  • The 30%, 40%, and 50% Humidity Indicator Cards comply with MS20003-2
  • The 5%, 10%, and 15% Humidity Indicator Cards comply with JEDEC Standard 033
  • 5%, 10%, -60% comply with JDEC Standard 033B

Cobalt Free

Cobalt-free humidity indicator cards (brown humidity indicator) have a copper chloride base that detects humidity and enables colour change from brown to azure (blue). The humidity sensor cards are free of cobalt chloride, making them safer. They comply with the European Community Council Directive 67/548/ECC.

Available in RH levels ranging from 5% to 60%

  • The 30%, 40%, and 50% Humidity Indicator Cards comply with MS20003-2
  • The 5%, 10%, and 15% Humidity Indicator Cards comply with JEDEC Standard 033
  • 5%, 10%, -60% comply with JDEC Standard 033B
