China Humidity Indicator Cards
HIC is a kind of visible card. Each dot on the card points one special relative humidity degree. The dot color will change along with the RH degree from blue to pink (common cobalt-containing HIC) or brown to green (cobalt-free HIC). This changing helps decide the inside RH degree and confirm whether the desiccant should be replaced or not.
