Bagged desiccant is intended for use in removing moisture from the air in packages and closed spaces to prevent corrosion, mold, mildew, and oxidation (rust).
A Humidity Indicator Card (HIC) is a simple-to-use instrument useful for measuring Relative Humidity (RH) percentage in any sealed environment, such as packaging. The HIC provides visual feedback of the RH percentage in the environment as a color change when exposed to a given percentage of RH. HICs are calibrated in different types to measure RH percentages from 5% to 60%. Humidity Indicator Cards are reversible by proper heating methods.
