Box Partners 1 9/16" x 4 3/4" Humidity Indicator Cards DES163 - 6-Spot 10%-60% Range (Case of 200)

Box Partners DES163 humidity indicator cards are compact, paper-based tools designed for quick, at-a-glance verification of internal moisture conditions inside sealed packaging. Each card features six color-changing spots that respond to relative humidity levels, shifting from blue (dry) to pink (humid) as RH increases. The six monitored points cover 10%, 20%, 30%, 40%, 50%, and 60% RH, providing a straightforward visual cue to whether protective moisture barriers or desiccant packs have maintained appropriate humidity levels during transit or storage. The small footprint—1 9/16" wide by 4 3/4" long—lets these indicators fit inside moisture barrier bags, vacuum-sealed pouches, or storage containers without adding bulk, making them suitable for handling volumes where space is at a premium.

These indicator cards are well suited for a variety of applications requiring quick, non-instrumental moisture assessment. End users can verify product integrity immediately upon opening sealed packaging, supporting quality control processes in receiving environments and helping to confirm that humidity exposure did not exceed thresholds that could compromise sensitive contents. The cards are sold in bulk cases containing 200 cards, enabling high-volume packaging and shipping operations to maintain consistent moisture monitoring without frequent reorders. The product originates from the United States and is categorized under office supplies, aligning with common packaging and documentation workflows. The DES163 model number is retained for precise part identification and compatibility within existing desiccant and moisture-control inventories.
