Product information

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

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.
