It does not use any cobalt compounds or heavy metals, making it very friendly to the human body and the environment.
This is a humidity indicator card that does not use any cobalt compounds or heavy metals, such as cobalt chloride (CoCl2·n-H2O) or cobalt bromide (CoBr2·n-H2O), which have generally been used as main components in humidity indicator cards. It is very friendly to the human body and the environment. The relative humidity change reversibly changes color from blue (when the humidity is lower than the indicated humidity) to pink (when the humidity is higher than the indicated humidity), exhibiting a similar color change to traditional cobalt chloride-based humidity indicator cards, allowing you to use it without changing specifications.
