Humidity Indicator Card - Color-changing Moisture Monitor | Reversible Visual Humidity Detection With Brown/blue To Azure/pink Transition

We are customer centric entity, engaged in manufacturing and supplying an Humidity Indicator Card in Dongguan, Guangdong, China. Humidity Indicator Card (HIC) is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity is exceeded in the sealed container.

An integral part of a complete moisture barrier packaging assembly is the Humidity Indicator Card. High Relative humidity can cause significant, possibly irreparable damage to sensitive equipment,supplies and products. To ensure dehydration measures work, Humidity Indicator Card measures the relative humidity (RH) inside sealed packages to allow immediate visual inspection of whether it has sustained unsafe humidity levels.

Instructions:
1. Humidity indicator card provides external monitoring of humidity levels inside containers and packages.
2. The humidity indicator spots will change from Brown/Blue (dry condition) to Azure/Pink (humid conditioni as the relative humidity changes in the volume of air surrounding the indicator.
3. The humidity indicator spots are reversible, and the Azure/Pink spots will change back to Brown/Blue when the volume of air is dried.
4. The highest humidity indicator spot should be Brown/Blue before being put into use.
