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 is in unacceptably high humidity levels. Usually packed with a desiccant and moisture barrier bag, HICs read humidity reliably and are compact, inexpensive, and easy to read. HICs are approved for MIL – I – 8835 applications with 30%, 40%, and 50% HIC complying with the MS20003-2 standard, 5%, 10%, and 15% HICs complying with JEDEC Standard 033 and the 5%, 10%, – 60% HICs with JDEC Standard 033B.

Our Humidity Indicator Cards are available in 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%, 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 (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. They comply with the European Community Council Directive 67/548/ECC.

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

  • The 30%, 40%, and 50% Humidity Indicator Cards comply with MS20003-2
