High relative humidity(RH) can cause significatn, possibly irreparable damages to sensitive equipment, electornics, semoconductors, and supplies. To ensure dehydration measures work, Humidity Indicator Cards(HICs) measure the relative humidity inside sealed packages to allow immediate visual inspection of whether it has sustained unsafe humidity levels.HICs are printed with moistue sensitive spots which respond to various levels of humidity with a visible color change from blue(dry), through lavender, to pink(humid).The humidity inside dry packed barrier bags can be monitored by including and...
