HUMIDITY INDICATOR CARD
-
Purpose
With the widest selection of humidity indicator (HI) cards for various industry applications, Humitector™ HI Cards provide simple, reliable, visual indication of the relative humidity within a sealed package or sealed environment.
-
What Are They?
Humitector Humidity Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Available in numerous configurations, Humitector cards indicate relative humidities as low as 5 percent and as high as 95 percent, depending on the application and need. There are two main types of humidity indicator cards: reversible and irreversible. Reversible humidity indicator cards work much like a thermometer, fluctuating to indicate the current relative humidity level. Maximum, or irreversible, cards are designed to indicate the highest relative humidity level to which goods have been exposed.
-
Why Use Them?
High relative humidity levels can cause irreparable damage to sensitive equipment, supplies, products and cargo. As such, many industries have instituted stringent packaging standards to protect goods from moisture as they are transported and stored throughout the supply chain. While many shippers and manufacturers might take the proper steps to protect their products from moisture, such as dry packing with desiccants, it is sometimes difficult to know how effective those steps are. Some products, such as electronic goods, often show no visual sign of moisture damage, while desiccants may reach their adsorption capacity before users realize they need to be replaced.
Humitector HI Cards provide visual proof of the relative humidity level within a given package environment. If the card indicates high levels of humidity, users know to replace their desiccant bags and check their products for possible damage. Clariant manufactures Humitector cards that comply with numerous industry and environmental standards. Without verifiable color accuracy, quality of devices could be compromised. Humitector cards are colormeter tested for color change accuracy within stringent industry parameters.
HUMIDITY INDICATOR PLUG
-
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 aluminium, 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 keep products dry.
-
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 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 are checked.
-
Usage Requirements
Mount 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°F.
-
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 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.
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.
CONTAINER DESICCANT
-
Purpose
To protect cargo from the harmful effects of moisture damage during shipping via container, rail, or truck.
-
What Is It?
Container desiccant is specially designed cargo desiccants aimed at protecting cargo during shipping by aggressively absorbing moisture from the air. In doing so, Container desiccant reduces dew point temperature (the temperature at which condensation begins to form, causing “container rain”), keeping cargo safe and dry. The Container desiccant includes several configurations to best fit different needs and modes of transport.
-
Why Use It?
As goods move through intermodal systems, they are susceptible to damage from excessive moisture. Container desiccant adds a level of protection by reducing the dew point to avoid the accumulation of condensation. Container desiccant absorbs up to three times its weight in moisture, and through an advanced formula, traps it as a thick, no-spill gel. Container desiccant has the ability to protect shipments from start to finish, through all temperature ranges and relative humidity variances, and continues to reduce the relative humidity down to levels below 40 percent RH, which decreases the dew point temperature even further.
