Usage Instructions

Color Change Principle

As ambient humidity rises, the indicator spots transition from their dry state color (yellow) to their moist state color (blue).

Reversible Functionality

When humidity decreases, the indicator spots revert from the moist color back to the dry color, enabling continuous monitoring.

Humidity Reading

The humidity value corresponding to the first fully changed indicator spot reflects the current environmental RH level.

Storage & Handling Precautions

Sealed Storage

Keep the humidity indicator cards in their original sealed metal cans or aluminum foil bags to prevent premature color change before use.

Desiccant Replacement

Replace the desiccant inside the packaging after the can has been opened three times to maintain dry conditions.

Environmental Protection

Store in a cool, dry area away from direct sunlight, water immersion, and high-humidity environments.
