R&D capabilityThe supplier claims advanced production lines, specialized machinery for humidity indicator cards and moisture-proof bags, a professional technical team, four R&D engineers, and ongoing product and quality development. These details provide positive evidence of technical and development capability, although no specific proprietary innovations or R&D achievements are documented.

Production capacityProduction capability is supported by 101 employees, an 11,000 m² manufacturing plant, more than 10 production lines, and stated capacities of 9,000 tons of desiccant and 3,000 tons of aluminum foil bags annually. The supplier also reports mechanized production lines and testing equipment, indicating substantial manufacturing infrastructure.

Client casesThe supplier states that Honda, Panasonic, Sony, and other well-known companies cooperate with it, and that its products are sold worldwide with good feedback. These are supplier-reported customer references; the slices do not include order details, verification, or named case studies.

Product Q&A

Q:What is the difference between reversible and irreversible HICs?

Reversible cards fluctuate to show current humidity levels, while irreversible (maximum) cards indicate the highest humidity level the goods have been exposed to.

Q:How long does it take for the indicator spots to change color?

Indicator spots change within eight hours of being exposed to a change in relative humidity.

Q:How can I reset a reversible humidity indicator card?

Place pink or lavender spots in a sealed container with 33 grams of desiccant for 48 hours to return them to blue.

Q:What are the storage conditions for these cards?

Store in a cool, dry area away from sunlight, water, steam, and ammonia gases. Keep in original sealed containers with desiccant.

Q:What standards do these humidity indicator cards meet?

They meet military specifications (Mil-I-8835, Mil-Std-2073-1D) and JEDEC standards (J-STD-033A/B).
