These humidity indicator cards deliver visual moisture monitoring across six calibrated thresholds — 10%, 20%, 30%, 40%, 50%, and 60% relative humidity — using a color-change mechanism that shifts from blue to pink as ambient humidity reaches each point. No instruments or tools are needed; personnel get an immediate, readable result at a glance.
These cards are well suited for electronics packaging, military and defense shipments, industrial components, pharmaceuticals, and archival storage — anywhere moisture exposure during transit or storage must be documented and controlled. Their 1 9/16" x 4 3/4" footprint fits standard desiccant pouches and moisture barrier bags without trimming or modification.
Each case contains 200 cards. The cards ship via parcel carrier, supporting routine replenishment for quality assurance programs in high-volume warehousing, contract manufacturing, and distribution environments.
