Brown 3 spots HIC 304050 (Cobalt-free)

Brown HIC (Cobalt-free) is used to test the humidity of the sealed package.  The percentage in the black circle on the HIC is the humidity value indicated in the circle. The user can quickly verify the humidity conditions in the product package and the status of the desiccant through the change of color indicating the humidity in the black circle on the card.The HIC is convenient, safe, reliable  to use. the color in the black circle on the card will slowly change from yellow color to light blue and meet the ROSH standard

If the humidity value of the environment is greater than the corresponding humidity value on the HIC, the color in the black circle on the card will slowly change from brown color to claybank, then from claybank to light blue; Otherwise, if  the humidity value of the environment is less than the corresponding humidity value on the HIC,the color in the black circle on the card will slowly change from light blue color to claybank, then from claybank to brown.

Special requirement of the humidity indicator card is customizable.
