Humidity Indicator Cards (HIC)
Reversible humidity indicator cards that change colour at set relative-humidity thresholds, for moisture-sensitive electronics, dry-pack, and export QC. Sourced and private-labelled to your specification.
Humidity indicator cards are the visual half of a dry pack: the desiccant controls the moisture, the card reports it. A QC operator reads a sealed pack's moisture state from the colour-changing spots without opening it. DryGelWorld sources and private-labels these cards to your specification, in cobalt or cobalt-free (REACH-friendly) chemistry and any spot layout, with compliance confirmed per supplied lot.
