IRREVERSIBLE HUMIDITY INDICATORS

Description of the irreversible humidity indicators

The irreversible humidity indicators allow to control the humidity to which the products are exposed inside the packaging.

The humidity indicators show if a critical humidity level has been reached or exceeded in the packaging, recording the maximum humidity reached.

In combination with desiccants, it reflects the moisture to which your product has been subjected, allowing you to draw conclusions about the state of your sensitive to moisture products.

Irreversible moisture indicators consist of white absorbent paper impregnated with a variety of colored salt solutions in different areas. The moisture content of the impregnated indicator fields changes according to the relative humidity (RH) of the surrounding air and, in addition, they change color.

Under standard conditions, the allowable tolerances with respect to the accuracy of the indicator are +/- 5% relative humidity. In conditions of extreme temperature, however, there may be a greater variation of this percentage. The humidity indicators comply with a variety of military specifications (TL, MIL, AFNOR).

We offer a wide range of irreversible moisture indicators in a variety of sizes, shapes and indicator areas, some of which have self-adhesive labels.
