Humidity indicators

Humidity indicator cards (HICs), which are mainly used for long-term storage and export packaging, indicate relative humidity (RH) inside a given barrier packaging. The indicator cards are impregnated with moisture sensitive spots that respond to various levels of humidity with a visible color change. The humidity indicator spots are reversible, and will change back to the original color when the humidity decreases.

Our standard humidity indicators offer detection across a wide range of humidity levels from 5% to 60% RH.

HICs can be used in the following domains, among others:

  • Electronic devices
  • Optical instruments
  • Export packaging
  • Bulk packaging
  • Military supplies
  • Packaged machinery and components

The HICs need to be placed inside the packaging. If the level of humidity should be seen from outside, humidity control windows need to be integrated into the barrier film.

Accuracy of HICs
HICs are easy and reasonably priced monitoring solutions with a tolerance of +/– 5 % RH. For more accurate measurement we recommend our g-log data logger.
