Product Introduction
In high humidity environments, semiconductor, electronic, electrical and other equipment and their components may cause certain damage. Humidity Indicator Card (HIC) is an environmental measurement product that detects whether the relative humidity inside a sealed packaging is safe.
By using a humidity indicator card, it is easy to determine whether the packaging of the product is safe, determine whether the desiccant inside the product packaging is ineffective, and warn to replace the desiccant in a timely manner to avoid the risk of moisture damage to the product. If the humidity inside the packaging reaches or exceeds this humidity value, the corresponding indicator dots on the card will gradually change from blue to pink; The humidity indicator card is reversible, and under low humidity conditions, the dots gradually change from pink to blue.
Therefore, if the corresponding dots on the humidity indicator card appear blue after opening the packaging container, it indicates that the sealing state is very safe, and thus it is judged that the packaging is safe.
So, humidity indicator cards are essential products for safe sealing. At 23℃The displayed humidity is the most accurate.
2. Main application areas
Semiconductors and electronic circuit boards (PCBs)\/electronic products\/warehousing\/military supplies\/organic materials\/optical instruments\/metal materials\/composite materials\/other packaging
3. Product features
*Convenient to use, easy to observe, and quickly determine humidity values
* The humidity indication range is large (RH5% to RHnine0
* The humidity indicator has high sensitivity and is 5% of the soil at the relevant temperature
* Reusable (dried and reused)
4. International\/domestic quality standards
*GJB2494-95(Military Standards of the People's Republic of China)

5. Storage
*The inner packaging consists of sealed bags and metal cans
*The humidity indicator card is sealed and stored in a packaging iron can, and desiccant is added. After the packaging is opened three times
Please replace the desiccant.
*Store in a dry and cool environment, avoiding direct sunlight and water immersion.
*The validity period of the humidity indicator card is 12 months when it is not opened and sealed for use
6. Humidity card absorbs moisture
Instrument required: One constant temperature and humidity box
Put the humidity card into the constant temperature and humidity box, set the RH value of the constant temperature and humidity box to the following humidity values, and the humidity card will have the following changes:
