Product Overview
Our Humidity Indicator Cards (HICs) are compact, cost-effective paper-based devices designed to monitor relative humidity (RH) levels in sealed environments. They are widely used in industries where moisture control is critical, such as electronics, semiconductors, and precision instruments.
Our HICs comply with the J-STD-033B industry standard, ensuring reliable and accurate moisture detection.
Key Features
Instant Detection
Changes color immediately when exposed to humidity, providing a clear visual warning.
High Sensitivity
Accurately detects RH levels at 10%, 20%, and 30%.
Reusable
Can be dried and reused multiple times, reducing operational costs.
Easy to Use
No external power or calibration required-simply place in the sealed package.
Cost-Effective
Low per-unit cost, making it ideal for high-volume applications.

How It Works
Initial State
The indicator dots are blue when the humidity is below the specified level.
Humidity Exposure
If the RH exceeds the threshold (e.g., 10%), the corresponding dot turns pink.
Reactivation
To reuse, place the card in an oven at 60–80°C (140–176°F) for 1–2 hours until the dots revert to blue.
Warning
Discard if the indicator dots overlap or show permanent discoloration. Avoid contact with metal surfaces.
