ShieldPro Humidity Indicator Card 10-Pack 10-60% 6 Dot (10 Cards)

Humidity Indicator Cards and Plugs provide a simple, reliable, visual indication of the relative humidity within a sealed package. High relative humidity levels can cause irreparable damage to sensitive equipment, such as semiconductors and military instruments. While many manufacturers take the proper steps to protect their products from moisture damage, such as using desiccants and moisture barrier bags, it is important to also ensure that these steps are effective. Some products, such as electronic goods, often show no visual sign of moisture damage in the event of a breach in the dry packaging system.
