Humidity Indicator Cards

Humidity Indicator Cards

These are small paper instruments, impregnated with a moisture-sensitive chemical(solution of Cobalt Chloride) and will change colour when subjected to excessive humidity levels (colour of blue changes to pink when saturated). They are an inexpensive way to quantify relative humidity levels inside sealed packaging. In case of semiconductors and military instruments, high relative humidity levels can cause irreparable damage. They are ideal to use with desiccant bags and desiccants, these confirm that your barrier bags and desiccants have functioned well. Also just by using a simple colour-coded system, humidity indicator cards indicate humidity conditions and inform the user when the desiccant bags should be changed. These small cards are placed within the moisture barrier bags and can be checked either upon arrival of the shipment or during the storage.
