Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Humidity Indicator Cards. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
These industrial humidity indicator cards provide a visible way to assess relative humidity inside sealed packaging. Each indicator dot corresponds to a specified relative humidity level and changes color when the indicated level is exceeded.
This allows personnel to inspect package conditions and determine whether desiccant replacement may be needed. Listed configurations include 5-10-60%, 30-40-50%, and 10-60%, as well as customized specifications.
The card material is paper, and sizing, packing, and transport packaging can be supplied according to requirements.
Listed indicator options include a cobalt-containing card changing from blue to pink, a cobalt-free card described as changing from brown to azure, and a cobalt-dichloride-free card described as changing from blue to pink. For storage, keep the cards sealed and dry and protect them from direct sunlight.
Before ordering, buyers should confirm the exact humidity thresholds, indicator chemistry, color-change sequence, card dimensions, printing or marking requirements, pack quantity, and packaging method.
Buyers should also request the applicable technical and compliance documentation for their intended market and application. Because multiple indicator formulations are listed, the required formulation should be identified explicitly in the purchase specification.
