Humidity Indicating Cards

Humidity Indicating Cards (HIC) provide a simple and effective way to monitor relative humidity levels inside sealed packaging. The humidity-sensitive spots change color when exposed to moisture, allowing users to quickly identify the RH level and take corrective action before moisture causes product damage.

Available in different RH ranges, including 8%, 10–30%, 10–40%, 5–15%, 20–40%, 30–50%, and 10–60% configurations. They are widely used for electronic equipment, PCBs, military equipment, tools, and moisture-sensitive products and can be used with desiccant pouches when humidity levels become excessive.
