Humidity indicator cards (HICs) are small strips that contain a moisture-sensitive chemical compound. They visually indicate the relative humidity (RH) level in a given environment.
HICs typically change colour or display a specific pattern in response to different humidity levels, providing a simple and quick way to assess the moisture content in the surrounding air.
Monitoring Humidity Levels
HICs are commonly used in various industries and applications where humidity control is crucial, such as electronics manufacturing, pharmaceuticals, food storage, and shipping.
They help to ensure that products, equipment, or sensitive materials are stored or transported within the desired humidity range to prevent damage, degradation, or spoilage.
Approved for use in MIL-I-8835 applications and comply with various standards such as MS20003-2, JEDEC Standard 033, and JEDEC Standard 033B. Humidity indicator cards are available in different humidity levels ranging from 30% to 60%.
Facilitates Verification of Moisture
Typically used with desiccants and moisture barrier bags, the humidity indicators are compact, inexpensive, and easy to read. Using humidity indicator cards, users can easily monitor and verify if the humidity conditions are within the specified range. This allows for timely interventions or adjustments to maintain the appropriate moisture levels.

Cobalt Dichloride Free HIC
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 HIC
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
