Maximum Irreversible Humidity Indicator Cards
Maximum Humidity Indicator Cards are specially designed cards that monitor relative humidity levels in cargo applications. Each level of humidity is represented by a blue crystal that dissolves to create a large blue spot that clearly indicates the highest relative humidity level that has been reached. Maximum Humidity Indicator Cards are irreversible, thus indicating the highest level of humidity experienced by cargo during its voyage, regardless of current (potentially lower) humidity levels. Maximum Humidity Indicator Cards provide a clear, unmistakable means of determining if goods have been exposed to damaging humidity levels during their journey. If the card indicates high levels of humidity, users know to check their products for possible damage or modify their packaging regimen accordingly.
