HUMIDITY INDICATOR PLUGS
PURPOSE
Humidity indicator plugs are designed to indicate the relative humidity level within a sealed container without users having to open it. Desiccator plugs both indicate and control humidity levels within the container.
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 steel, they feature large, clear viewing windows for easy reading of humidity levels within the container.
WHY USE THEM?
Sensitive goods are often housed in containers that either should not or can not be opened until use. By installing humidity indicator 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 are checked.
USAGE REQUIREMENTS
Humidity indicator plugs internally on flexible barriers, plastic and fiber bags, rigid equipment, electrical housing and other humidity controlled spaces.
Indicators are reversible and fluctuate with current relative humidity levels. Indicators are accurate within 5 percent when read at 75 Fahrenheit degree .
STORAGE AND HANDLING
Store plugs in their original shipping container until ready for installation.
Do not put indicators in direct contact with water or steam, as they are water-soluble. Ammonia gases will also damage indicators.
AVAILABLE CONFIGURATIONS
Humidity indicator 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.
Plugs are adaptable to virtually all applications for military packaging of Mil-Std-2073-1 Method 50 and AS26860 aerospace specifications. Compact plugs are designed to be leak- resistant and temperature-proof, and to withstand shock and vibration.
