A humidity indicator card that is very friendly to the human body and the environment!
The "PBP3V/10-30" is a Co-Free 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 the main components in humidity indicator cards. It is very friendly to both the human body and the environment. The relative humidity changes color reversibly to blue (when the humidity is lower than the indicated humidity), lavender (indicated humidity), and pink (when the humidity is higher than the indicated humidity), providing a similar color change to conventional cobalt chloride-based humidity indicator cards, allowing it to be used without changing specifications. 【Features】 ■ Very friendly to the human body and the environment ■ Does not use any cobalt compounds or heavy metals *For more details, please refer to the catalog or feel free to contact us.
