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 paper humidity indicator cards provide a visual means of checking relative humidity inside sealed packaging. The indicating dots change color as humidity conditions change, allowing packaging personnel to inspect the reported humidity level without an electronic instrument.
The cobalt-free version is described as changing from brown to green. A blue-to-pink change is also listed for conventional humidity indicator cards, so buyers should specify the required chemistry and color-change system when ordering.
Standard configurations include cards indicating 5%, 10%, 15%, 20%, 30%, 40%, 50%, and 60% relative humidity in different point combinations. Listed formats range from three to six indicating points, with card dimensions of 42 × 92 mm, 51 × 76 mm, or 38 × 102 mm depending on the item.
The stated customizable indication range is 10%–90%. Reported applications include packaging for printed circuit boards, integrated circuits, semiconductors, and surface-mount LEDs.
The cards are intended to help users observe humidity conditions within such packaging;the supplied facts do not establish moisture prevention, drying performance, or suitability for any particular storage standard. Procurement confirmation is important because the supplied packaging information is inconsistent.
The configuration table states 200 cards per can and 5,000 cards per box, while another description lists 20 cards per vacuum pack, 250 cards per can, and 5,000 cards per carton.
Buyers should confirm the exact inner packing, can quantity, outer-carton quantity, card format, indication points, color-change chemistry, and labeling before purchase.
The product information also references RoHS and ISO in the specification field, but it does not identify a standard number, certification scope, test report, or issuing body. Buyers requiring compliance evidence should request and review current documentation for the exact ordered model and production batch.
Shelf life, storage conditions, activation tolerances, reading accuracy, response time, reversibility, and warranty are not stated and should also be confirmed for the intended packaging process.
