Irreversible Indicator Cards

Permanent Visual Proof of Excess Humidity Exposure

CCD Enterprise’s Irreversible Humidity Indicator Cards are designed to provide permanent visual evidence when humidity levels within sealed packaging exceed specified thresholds. Unlike reversible cards, these indicators change color permanently, serving as a tamper-proof record of moisture exposure for sensitive electronics, semiconductors, pharmaceuticals, and other critical products.

These cards are ideal for quality assurance, compliance verification, and dry pack validation – especially in environments where humidity excursions must be recorded and cannot be reversed.

Key Features

Permanent Color Change: Irreversible reaction indicates if RH exceeds set levels

Available RH Levels: 5%, 10%, 30%, 40%, 50%, 60% (single or multi-spot formats)

Clear Visual Indicator: Spot changes color once threshold is exceeded – does not revert

Card Formats: 1-spot, 3-spot, 6-spot available

Compliant With: JEDEC J-STD-033, RoHS, and REACH

Packaging: Foil vacuum-packed for shelf life protection

Custom Options: Printing, logo, or barcoding for traceability

Applications

Moisture-sensitive device (MSD) dry packing

Semiconductor IC, PCB, and sensor packaging

Export shipments requiring quality verification

Military, aerospace, medical, and optical assemblies

Controlled humidity packaging (MBB + desiccant + HIC kits)
