Product Introduction

Our humidity indicator card (HIC) is a compact, paper-based device designed to monitor relative humidity (RH) levels in sealed environments. Each circular indicator is marked with a corresponding RH percentage, providing a clear, visual reference for moisture conditions.
Compliant with the JEDEC standard J-STD-033B, our humidity indicator cards deliver reliable, industry-recognized performance. They are an essential tool for moisture-sensitive electronic components, ensuring compliance with global storage and shipping requirements.

Key Features

User-Friendly & Instant Readout

Easy to observe, allowing for quick and accurate RH level determination.

Wide Humidity Detection Range

Covers 10%–60% RH to suit diverse environmental monitoring needs.

High Sensitivity

Delivers precise and responsive color changes to even minor humidity fluctuations.

Reusable Performance

Can be restored to its original state by drying, offering long-term cost efficiency.

Important Notes

Store humidity indicator cards in their original sealed cans/aluminum foil bags to ensure color stability before use.
Replace the desiccant inside the packaging after it has been opened twice.
Keep in a dry, cool environment, protected from direct sunlight and water immersion.

Industry Applications & Scenarios

Electronics & Semiconductors

Production Line Storage: Monitor RH levels in sealed packaging for PCBs, IC chips, and SMD components to prevent solder joint oxidation and device failure.

Long-Term Warehouse Storage: Ensure the reliability of electronic components during extended inventory periods.

International Shipping: Validate moisture barrier effectiveness for sea and air freight, protecting against humidity damage in high-humidity transit environments.

Military & Aerospace

Defense Equipment Packaging: Safeguard precision military electronics, avionics, and communication devices in harsh field conditions and long-term storage.

Aerospace Component Protection: Maintain the integrity of satellite and aircraft electronics that are sensitive to even trace amounts of moisture.

Optics & Precision Instruments

Camera & Lens Storage: Prevent fogging and lens coating degradation in sealed camera and optical equipment cases.

Medical Device Packaging: Ensure sterility and performance of diagnostic sensors, lab equipment, and implantable devices by monitoring RH levels in sterile packaging.

Metal & Hardware

Automotive Parts Storage: Protect engine control units (ECUs), sensors, and precision metal components from corrosion during warehouse storage and shipping.

Industrial Tool Preservation: Maintain the performance of high-precision machining tools and measuring instruments by preventing rust and moisture damage.

Moisture Barrier Packaging Validation

Vacuum Packaging Quality Check: Verify that vacuum-sealed packaging for sensitive goods remains intact and moisture-free.

Desiccant Performance Monitoring: Confirm that desiccants in sealed packaging are still effective by tracking RH changes over time.
