Humidity indicator cards provide external monitoring of humidity levels inside containers and packages. AGM’s Humidity Indicators meet various SAE Specifications.

Rectangular humidity indicator cards include both Reversible and Non-Reversible Humidity Indicator Cards. AGM’s cards can be used in conjunction with AGM’s Desiccant and Breather Valves to provide a complete environmental control system.

Reversible color-change discs are intended to serve as visual indicators that a given humidity level specified on the disc has been exceeded. These chemically impregnated discs are made from blotting paper, and are manufactured in accordance with MIL-I-8835. Humidity Indicator discs may be ordered pre-installed as a complete Humidity Indicator assembly (please refer to AGM's Humidity Indicator Plugs) or may be installed in any SAE AS26860 type plug.
