What is humidity indicator card？
Humidity card is also called humidity indicator card, humidity display card, humidity detection card, humidity discoloration card, moisture-proof label, moisture-proof card, moisture-proof indicator, ETC. The humidity card is a visual card. The user can judge whether the relative humidity RH of the product in the airtight package is safe to measure the product through the color change of the card. Each color point in the card represents a humidity value. The value changes gradually from the dry color to the wet color, the humidity card can save the product from the danger of getting wet.
特征:
1. When the humidity of the surrounding environment of the humidity indicator card increases to a certain value, the corresponding indicator point on the indicator card will change from color to color.
2. The color change of the indicator point is reversible. When the air around the indicator card dries out, the color of the indicator point changes back to its original color.
3. When the indicator point changes color, the value in the indicator point is the current ambient humidity
4. Humidity card with rounded corners is beneficial to effectively protect the function of pierced packaging, and can effectively prevent the liquid from the humidity card from contaminating the layout.
5. Keep the humidity indicator card tightly sealed in the original packaging tin can, and put in the desiccant.
