Indicating Desiccant Bags
Know when it's time to change these desiccants—they turn from blue to pink after absorbing 8% of their weight. Use to remove moisture from sealed containers during shipping and storage.
These desiccants are best when relative humidity is at least 40%. The area covered is calculated at 77° F and 40% relative humidity.
The bags have a monitoring window to check for desiccant color change.

High-Humidity Desiccant Bags
When relative humidity is at least 90%, use these desiccants. They are often used to protect cargo sent in large containers from moisture.
The area covered is calculated at 77° F and 90% relative humidity.
Thirty-two 10 1/4" long desiccant bags are recommended for a 20-ft. shipping container.
22" long desiccant bags are best for large sea containers, rail cars, and river barges. They have a hanging strap and a locking carabiner, so you can secure them off the floor to save valuable floor space. Three bags are recommended for a 20-ft. shipping container.

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.

Through-Wall Humidity and Temperature Meters
Monitor relative humidity, temperature, and dew point inside sealed containers. These meters are rated IP67, so they won't expose contents to dust and water. The housing is aluminum, which is lightweight and resists corrosion.

Corrosion-Inhibiting Packs
Toss these packs into your shipping box to stop metals from corroding, oxidizing, tarnishing, and discoloring. These packs emit vapors that are absorbed by metal surfaces, creating a protective barrier. They're also known as volatile corrosion inhibitor (VCI) vapor packs.
