Humidity Indicator & Desiccator Plugs

Applications:

What are they?

Humidity indicator plugs work much like Humidity Indicator Cards but can be screwed into the outside walls of sealed containers. Made of aluminum, brass or stainless steel, they feature large, clear viewing windows for easy reading of humidity levels within the container. In the case of desiccator plugs, a desiccant tube extends from the indicator into the container to maintain a dry environment.

Why use them?

Sensitive goods are often housed in containers that either should not or can not be opened until use. Often, plugs are used on equipment, components or devices that otherwise would never be opened unless there is an issue. By installing humidity indicator or desiccator plugs into the walls of these containers, users can ensure that goods are housed at safe humidity levels without exposing them to external elements while humidity levels can still be checked.

Available configurations

Süd-Chemie’s humidity indicator and desiccator plugs are available in a variety of sizes and configurations, detecting anywhere from 5 to 95 percent relative humidity. Plugs are compatible with rigid-wall equipment and electrical housings, as well as most flexible barriers. Desiccator plugs are primarily designed for small containers, mechanical boxes or sealed instruments where space is limited.

Observation window and porous desiccator attachment components are available separately when applicable.

Plugs are adaptable to virtually all applications for Method II packaging of Mil-Std-2073-1D Method 50 and AS26860 aerospace specifications. Compact plugs are designed to be leak-resistant and temperature-proof, and to withstand shock and vibration.
