10-60%湿度指标卡

humidity indicating cards for indicating humidity conditions. The humidity-indicating cards are intended for us to determine that the desiccant within a package is sufficiently active to maintain a relative humidity below that at which corrosion might occur. The cards may also be used in any application in which a knowledge of the approximate relative humidity within a closed space is desired. It is widely used with Vitasorb clay desiccant and Vita-Shield Static Shielding bag to form a perfect package solution for electronics device, semi-conductor.
