Humidity Indicator Card

A Humidity Indicator Card is a visual tool used to monitor the moisture level inside sealed packaging, such as electronic components or pharmaceuticals. It contains small color-changing spots made from humidity-sensitive chemicals. When exposed to different humidity levels, these spots change color, allowing users to easily assess whether the environment remains within acceptable moisture conditions. This helps prevent damage caused by excess moisture, ensuring product quality and longevity. The cards are simple to read and do not require any special tools, making them an effective way to verify proper packaging integrity during storage and transportation.
