These 2x3 inch humidity indicator cards deliver a tool-free, visual method for monitoring moisture exposure inside sealed packaging. Each card tracks three relative humidity thresholds — 30%, 40%, and 50% — using a color-change reaction that displays blue under dry conditions and shifts to pink as humidity rises past each marked level.
Humidity indicators are placed inside sealed bags or containers alongside desiccants to confirm that moisture control measures are performing as intended. Common applications include electronics packaging, optical equipment, aerospace and military components, pharmaceuticals, and moisture-sensitive industrial parts held in long-term warehouse storage.
Cards are printed on a compact format that fits inside most standard packaging configurations without displacing product volume. Each case contains 125 indicator cards and ships via parcel carrier.
