Humidity Indicator Cards

With the help of Humidity Indicator Cards, levels of humidity can be externally monitored within the packages and containers. These cards are mainly blotted papers that are impregnated with  chemicals such as Cobalt(II) or copper(II) with the base chloride. By applying these chemicals, the cards are made highly sensitive to the moisture so that they can easily change their color during increase in the relative humidity. Also used in various cargo applications to determine whether goods have been exposed to the humidity level during their journey. Humidity Indicator Cards appear blue to pink and pink to blue as there is increase or decrease in humidity level, respectively.

Key Benefits:
  • Can be provided with reversible discs that act as visual indicators to determine the humidity level.
  • Ideal solution for quantifying the levels of relative humidity within the sealed packaging.
  • Used for conjunctions for rendering a control system for the environment.
  • Available in a number of configurations to fulfill the requirement.
