HUMIDITY INDICATOR CARDS (HIC)

Humidity Indicator Cards (HIC) are essential for verifying the effectiveness of moisture barrier packaging and desiccants. These cards provide a clear visual indication of relative humidity levels inside sealed packages by changing color — typically from blue (dry) to pink (humid).
By checking the card when opening a package, users can quickly determine whether the contents have been exposed to excessive moisture and if corrective actions such as baking or repackaging are required.
Humidity indicator cards are widely used in electronics, aerospace, military, and industrial packaging applications where moisture control is critical.

HOW TO READ THE CARD
Each circle on the card represents a specific humidity level (for example: 5%, 10%, 60% RH).
- Blue = Dry (Safe condition)
- Pink = Moisture present (Action required)
General Guidelines:
- If the higher humidity level (e.g., 60%) shows pink, components may need baking before use
- If lower levels (5% or 10%) turn pink, consider changing desiccants and resealing
- Always inspect the card immediately upon opening the package
