Product Introduction
The Cobalt-containing Humidity Indicator Card (HIC305) is a compact, paper-based instrument designed to monitor and display relative humidity (RH) levels in sealed packaging environments. The percentage values marked above or next to the indicator dots represent the corresponding RH threshold for that dot.
This product fully complies with the JEDEC Standard J-STD-033B, meeting international regulatory requirements for moisture-sensitive device (MSD) protection across industries like electronics, semiconductors, and optoelectronics. It provides a reliable, cost-effective solution for verifying the effectiveness of dry packaging and desiccants.
Key Features
User-Friendly
Intuitive color change for quick, visual RH level assessment.
Wide Detection Range
Covers critical humidity points (5% / 10% / 60% RH) for MSD protection.
High Sensitivity
Delivers accurate, immediate response to humidity fluctuations.
Reusable Performance
Can be regenerated by drying (baking) for multiple cycles of use.
Reversible Color Change
Dots revert from pink back to blue as humidity decreases, enabling continuous monitoring.
Important Handling & Storage
Pre-Use Storage
Keep cards sealed in their original iron can or aluminum foil pouch until use to ensure indicator dots remain blue.
Desiccant Maintenance
Replace the desiccant inside the can after the package has been opened 3 times.
Ideal Storage Conditions
Store in a cool, dry area, away from direct sunlight and water immersion.
How It Works
Humidity Increase
As ambient RH rises, the indicator dots change from their dry state (blue) to their humid state (pink).
Humidity Decrease
The card is reversible-pink dots will revert to blue if the environment becomes drier.
Reading the RH Level
When a dot changes to the specified humid color, the value next to that dot indicates the current RH level of the environment.
