Humidity Indicator Card

1. Product Introduction

Humidity Indicator Card (HIC) is a moisture sensitive paper that will change color when the indicated relative humidity is exceeded, we can know the humidity from the card directly and avoid the humidity damaging the product.

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.

2. 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 condition）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.

(5) The Temperature at 23°C ,when RH exceeded 5% of the indicator value, color spots are Azure/Pink, if the RH is under the indicator value, color spots are Brown/Blue.

(6) Avoid the Humidity indicator cards directly contact with liquid water or metal. 

3. Applications

Widely used in Printed Circuit Board, PCB, LED, SMD, IC, wooden toys, stuffed toys, electronic packaging, optical equipment, electronic equipment packaging, electronic products, optical components, military products, metal products, organic materials, synthetic material, protective packaging, moisture sensitive components packing.
