Our Humidisorb™ Moisture and Corrosion Control Packets are filled with a proprietary, self-regenerating desiccant designed to maintain a consistent relative humidity in any enclosure. Unlike traditional desiccants, which absorb as much moisture as possible before the end of their effectiveness, Humidisorb™ controls its environment’s relative humidity by absorbing and releasing moisture until it comes to equilibrium. Once established, it maintains that relative humidity, protecting sensitive electrical components and extending their working life. Humidisorb plus X-Corrode™, provides moisture and corrosion control for electrical components where conformal coating is not feasible, such as dip switches. The addition of X-Corrode to standard Humidisorb™ also extends the life of the packet from approximately two years to typically ten.
