Humidity Indicator Cards

Humidity Indicator Cards are small, paper or plastic cards that contain chemical or moisture-sensitive materials that change colour in response to changes in humidity levels. They monitor and indicate the relative humidity (RH) or moisture content in a sealed environment, such as a container or packaging, where moisture control is crucial to protect sensitive products or materials.
