Humidity indicator card
■Performance
Humidity indicator card (Humidity Indicator Card, HIC) is used to display the ambient humidity inside the package. At the same time, it can also be determined whether the desiccant inside the package can effectively maintain the low humidity inside the package to prevent the product from getting wet. The Humidity Indicator Card (HIC) is a card with a color-changing circle dot that allows the user to easily identify the ambient humidity in a sealed container or confined space and the use of the desiccant in it. When the color on the humidity display card changes from blue to pink, it is determined that the humidity in the packaging container has reached the level of damage to the item or that the container desiccant has failed. In a high humidity environment, semiconductors, electronics, electrical appliances and other equipment and their parts may cause certain damage. It is better used with our high-efficiency desiccant and anti-static shielding bag, which is widely used in the packaging set of semiconductor and electronic products. It is an environmental measurement tool to detect whether the relative humidity in a closed package is safe, and it is the most economical hygrometer at present.
Merit:
