Introduction to Humidity Indicator Card
A humidity indicator card (HIC) is a simple yet crucial tool used to monitor the relative humidity within a sealed environment. It contains chemical indicators that change color based on the humidity level. These cards are widely used in various industries such as electronics, pharmaceuticals, food, and aerospace to ensure that products are stored and transported under optimal humidity conditions. By quickly and visually indicating the humidity status, humidity indicator cards help prevent damage caused by excessive moisture, such as corrosion, mold growth, and degradation of sensitive materials.
