Humidity Indicator Card to Monitor your Desiccant

Here is a quick, easy test to see if your desiccant is working inside a sealed package or closed space. Simply pack one of these cards in with the contents and desiccant. Then examine the card on arrival at destination or periodically during storage. Any color change from blue to pink indicates an unsealed container or a high level of humidity.
