Operating requirements
Humidity indicators can be installed in soft moisture-proof bags, plastic and fiber bags, hard equipment, electrical components, and other humidity control spaces.
Indicator card is reversible and fluctuates with the current relative humidity level. Indicator card readings are accurate to within 5% when reading at 24°C.

-Store indicators in their original container until ready for installation.
-Do not allow the indicator to come into direct contact with water or steam because the indicator card is water-soluble. Ammonia can also damage the indicator.
