It can detect and display relative humidity from 50% to 90% in 10% intervals.

The humidity management maximum humidity indicator card can detect and display relative humidity from RH 50% to 90% in 10% increments. The principle is that after more than 24 hours, the blue crystals in the center dissolve into the surrounding area, indicating the relative humidity.

Cobalt-free humidity indicator card

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. For more details, please contact us or refer to the catalog.
