Humidity Indicator Card
■ Performance
The humidity indicator card (humidity display card, humidity card, Humidity Indicator Card, HIC) is used to display the environmental humidity inside the packaging. It can also determine whether the desiccant inside the packaging can effectively maintain a low humidity to prevent the product from getting damp. The humidity indicator card (HIC) is a card with color-changing circular dots. Users can easily identify the environmental humidity and the usage status of the desiccant inside the sealed container or closed space by observing the color change of the dots. When the color on the humidity display card changes from blue to pink, it indicates that the humidity inside the packaging container has reached a level that can damage the items or the desiccant has failed. In a high-humidity environment, semiconductors, electronics, electrical equipment, and their components may suffer certain damage. It is best to use it in combination with our high-efficiency desiccant and anti-static shielding bags. It is widely used in the packaging of semiconductors and electronic products. It is an environmental measurement tool for detecting whether the relative humidity inside a sealed package is safe and is currently the most economical hygrometer.
Advantages:
· Easy to use, easy to observe, and quick to determine the humidity value
· Wide humidity indication range (RH5% to RH90%)
· High humidity indication sensitivity, ±5% of the relevant humidity
· Reusable (can be reused after drying)
■Judgment:
When the humidity around the humidity indicator card rises to a certain level, the corresponding indicator points on the card will change from blue to pink. The color change of the indicator points is reversible. When the air around the indicator card becomes dry, the color of the indicator points will change back from pink to blue. When the indicator points turn purple (between blue and pink), the value indicated by the points represents the current environmental humidity.
Note: Customization/production available upon customer's request (lead time: 5-7 days)
■ Standards:
· GJB2494-95 (Military Standard of the People's Republic of China)
· MIL-I-8835A (U.S. Military Packaging Standard)
· IPC/JEDEC J-STD-033B (Standard of the Electronic Components Industry Association)
■Storage:
- Inner packaging: sealed bags and metal cans; outer packaging: cartons, 36 cans * 250 pieces/can = 9000 pieces/carton.
- Carton size: 467 * 360 * 415 mm
- The humidity indicator card is sealed in the packaging tin and desiccant is included. Please replace the desiccant after opening the package three times.
- Store in a dry and cool place, avoiding direct sunlight and water immersion.
Usage Notes:
The indicator card must be placed in the same container with the items to be dried.
The humidity card must not come into contact with water, oil, toluene or any other solvents.
The humidity card will change color back and forth according to the humidity level of the environment, but it will lose its function if the humidity exceeds 60%.
Humidity cards cannot be used in high-temperature environments (above 100°C).
The humidity card must be stored in a dry environment (with a relative humidity of less than 60%).
The humidity indication is correct, with an error within ±5% of the relative humidity.
■ Application:
It is widely used in semiconductors, printed circuit boards (PCBs), optical instruments, ICs, integrated circuits, packaging of electronic components, warehousing, military supplies, organic materials, optical equipment, metal materials, composite materials, and various high-standard vacuum packaging products.
