The HIC 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. If the humidity value of the sealed environment is greater than the corresponding humidity value on the HIC, the color in the black circle on the card will slowly change from dry color to humid color. The HIC is convenient, safe, reliable and convenient to use.

Q: What's Humidity Indicator Cards?
A: The HIC 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. If the humidity value of the
sealed environment is greater than the corresponding humidity value on the HIC, the color in the black circle on the card
will slowly change from dry color to humid color
