Humidity Indicator Card (HIC)

HIC allows fast visual inspection of the Relative Humidity (RH) in sealed packaging and containers. As the humidity increases, the chemically impregnated spots will be changed traditionally from blue to pink (Cobalt-HIC), blue to pink (CDF-HIC), brown to green (CB-HIC), yellow to green (CF-HIC) and green to purple (MF-HIC). Our HICs have 3 spots or 6 spots, but we also have a one spot type. It contains 3 spots, but only one spot is chemically impregnated and other two spots are just printed with reference colors for “OK” and “NG” (not good) so that user can easily check if it is failed or passed according to acceptable preset limit (ex. Semiconductor -10% RH, PCB/LED – 30% RH, etc.) in each industry.
We also have a plug type in round shape different from most other square designs in the market. Especially, if we use it with a specially designed plug case, it will become a lot easier and effective to check the humidity conditions inside of the bags without opening them.
