Humidity Indicator Cards

With the widest selection of humidity indicator cards for various industry applications, we provide simple, reliable, visual indication of the relative humidity within a sealed package or sealed environment.

What are they? Humidity Indicator Cards are small, paper instruments designed to monitor relative humidity levels. Available in numerous configurations, they indicate relative humidities as low as 5% and as high as 95%, depending on the application and need.

Humidity Indicator Cards provided by James Dawson are often used in conjunction with a desiccant and a moisture barrier bag in shipping, to ensure the quality of semiconductors, military equipment and sensitive devices by protecting them from excessive moisture.

Specs

There are two main types of humidity indicator cards: reversible and irreversible. Reversible humidity indicator cards work much like a thermometer, fluctuating to indicate the current relative humidity level. Maximum, or irreversible, cards are designed to indicate the highest relative humidity level to which goods have been exposed.
