Humidity Indicator Card

Humidity Indicator Cards (HICs) have moisture-sensitive spots which detect and change from blue to pink according to the humidity level in the surrounding environment, allowing users to quickly identify when a product has been in unacceptably high humidity levels. Usually packed with a desiccant and moisture barrier bag, HICs read humidity reliably, are compact, inexpensive, and easy to read. HICs are approved for MIL – I – 8835 applications with the 30%, 40%, 50% HIC complying with the MS20003-2 standard, the 5%, 10%, 15% HICs complying with JEDEC Standard 033 and the 5%, 10%, – 60% HICs with JDEC Standard 033B.

Our Humidity Indicator Cards are available in both Cobalt Dichloride Free and Cobalt Free.

Cobalt Dichloride Free

Cobalt Dichloride Free Humidity Indicator Cards (also known as blue humidity indicator cards) 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.

They are available in RH levels ranging from 5% to 60%.

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

Cobalt Free Humidity Indicator Cards (also known as brown humidity indicator cards) have a copper chloride base that detects humidity and enables colour change from brown to azure (blue). These humidity sensor cards are developed to be free of cobalt chloride, making them safer to use. They are compliant with the European Community Council Directive 67/548/ECC.

They are available in RH levels ranging from 5% to 60%.

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