?Portable & Durable Silica Gel Desiccant Containers?: 800g sturdy metal canister is designed with perforated mesh sides, filled with regenerable silica gel. Indicating silica gel desiccant containers are strong and resistant to dents, while the spray-painted exterior prevents rust. The can features a removable lid, and the top cap can be unscrewed to easily empty the contents. Its independent and portable design offers convenience in both usage and storage. Effective volume of 600 cubic feet. ?Blue Indicating Silica Gel Beads?: Wisesorb blue indicating beads (2-4mm in size) are designed to change color within a humidity range of 20%-50%. Once saturated with moisture, the beads will complete the color change to pink. It's important to note that the initial color change does not indicate full saturation. The beads will continue to absorb moisture until reaching 50%RH. We recommend periodically checking the silica gel beads to ensure their effectiveness. ?See-Through Plastic Disk, Transparent Window?: Wisesorb desiccant canister features a clear window that allows you to check the color of the beads without opening the container. If the beads change from blue to pink, it indicates that the environmental relative humidity is above 50%. With an effective volume of 600 cubic feet, it provides efficient moisture absorption. ?Easy Reactivation?: To reactivate the reusable silica gel canister desiccant dehumidifier, simply place it in the oven at a temperature of 200°F-250°F for 0.5-3 hours (avoid exceeding 250°F), and the beads will turn blue again. Depending on the condition of the silica gel beads, reactivation may take less time than the recommended duration. Remember to regularly check the color of the silica gel beads. ?Versatile?: Silica gel container can protects up to 600 cubic ft of enclosed storage space., including safes, ammo cans, toolboxes, 3D printer filament storage boxes, weapon cases, and closets.
