Humidity Indicator Cards monitor moisture levels by changing colour when humidity exceeds safe limits. Ideal for electronics, pharmaceuticals, and packaging, they provide a low-cost, efficient way to detect moisture exposure. Used alongside desiccants and barrier packaging, they ensure optimal product protection and easy humidity tracking.

Monitor and control moisture levels in sealed packaging with our Humidity Indicator Cards (HICs)—a low-cost, efficient, and accurate solution for industrial humidity testing. Designed for electronics, pharmaceuticals, and moisture-sensitive products, these color-changing indicator cards provide instant humidity detection, ensuring optimal storage and protection.
How Humidity Indicator Cards Work:
- Blue dots turn pink when the specified humidity level is reached, providing clear visual evidence of moisture exposure.
- Used alongside desiccants and moisture barrier bags to validate moisture control measures.
- Available in multiple humidity ranges (8% - 90%), making them ideal for various industrial and packaging applications.
Key Benefits:
- Cost-effective & simple to use – A non-electric, accurate humidity monitoring tool
- Instant moisture detection – Provides clear and reliable humidity readings
- Essential for moisture-sensitive items – Used in electronics, pharmaceuticals, and industrial storage
- Packaged in vacuum-sealed packs of 25 – Ensures long shelf life and usability

A Humidity Indicator Card is a simple paper-based tool that changes colour to show the relative humidity inside sealed packaging or storage environments.
Humidity Indicator Cards work alongside desiccants to confirm that moisture levels remain controlled, giving users visible proof that the packaging environment is protected.
Humidity Indicator Cards provide a reliable visual indication of relative humidity but should be used as a guide, not a precision instrument.
No. Once exposed to moisture and the colour change occurs, a Humidity Indicator Card should be replaced for continued accuracy.
They are widely used in electronics, medical device packaging, aerospace, and any industry where humidity control and monitoring are critical.
