Humidity-Indicating Cards
Check humidity levels of moisture-sensitive inventory and equipment at a glance. To detect moisture exposure when packaging, shipping, and storing electronics and chemicals, these cards have dots that change color as humidity levels change. Store electronics in a moisture barrier bag with one of these cards and a desiccant bag (bags not included). To revert these cards to their original color, place them in a dry container for 24 hours or bake at 180° F for 3 hours. Cards will not revert to their original color once they reach 60% or greater humidity. They meet industry guidelines for packaging moisture-sensitive devices.
Cobalt-free cards have a lower impact on the environment than cards that are not cobalt-free.

Humidity-Indicating Plugs
Monitor humidity in sealed containers without opening them, protecting the inside from contamination. These plugs are often used on plastic bags, storage containers, and electrical housings. Consisting of a mounting nut and two gaskets for a tight seal, these plugs install through a hole in a flexible barrier. Remove one gasket and reverse the nut to install plugs in a rigid container. Watch the indicator disc through the nut’s viewing window—it will change color as humidity rises and falls. Made of anodized aluminum, these plugs resist corrosion and are lightweight. They meet military and SAE standards for humidity indicators.
