Humitector® Humidity Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Available in numerous configurations humidity indicator (HI) cards cover various industry applications, Humitector® HI Cards provide simple, reliable, visual indication of the relative humidity within a sealed package or sealed environment.
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.
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.
