Product Overview
Our 3-Spot Cobalt Humidity Indicator Card (HIC) is a precision paper-based device designed to monitor relative humidity (RH) levels in sealed environments. It meets the strict requirements of the JEDEC standard J-STD-033B, making it ideal for moisture-sensitive electronic components, PCBs, and precision instruments. With a clear color-change mechanism, it provides a fast, reliable way to detect moisture ingress and protect your products during storage and shipping.

Key Features
User-Friendly Design
The three clearly marked humidity spots (30%/40%/50%) allow for instant visual inspection of humidity levels, eliminating the need for additional equipment.
Wide Humidity Range
Covers the critical RH thresholds for moisture-sensitive devices, providing comprehensive protection.
High Sensitivity & Accuracy
Color change is precise and meets JEDEC J-STD-033B standards, ensuring reliable moisture detection.
Reusable Performance
Can be regenerated by baking at low temperature (105°C for 1–2 hours), reducing operational costs.
Applications
Our humidity indicator cards are widely used across industries to safeguard moisture-sensitive items:
- Semiconductors & Electronics: ICs, PCBs, LED modules, and electronic components
- Military & Aerospace: Precision avionics and defense equipment
- Optics & Optoelectronics: Lenses, cameras, and laser components
- Metal & Composite Materials: Preventing corrosion and degradation
- General Industrial Packaging: Vacuum-sealed storage for sensitive goods
Packaging & Handling
- Storage: Keep cards in their original vacuum-sealed can/aluminum foil bag until use. Ensure indicator spots remain blue before installation.
- Usage: Place one card inside each sealed package alongside desiccant.
- Precautions:
a. Replace desiccant after opening the package three times.
b. Store in a dry, cool environment away from direct sunlight and water immersion.
c. Avoid contact with metal surfaces to prevent contamination.
