The card is equipped with reversible reading spots of the relative humidity. It is cobalt-dichloride free, and can change its color from blue to rose when relative humidity level is exceeded. The humidity indicator is packed in an enclosure that allows user control, and is available in different versions. It monitors low relative humidity levels of 5%, or a maximum of 95% HR, depending on the application and requirements.

The Propasecard is easy-to-use and readable. It has blue spots in the absence of moisture, and turns to pink if a different indicated humidity level is reached.
