Humidity Indicator Card
Humidity cards are divided into cobalt and cobalt-free:
There is a cobalt humidity card (not in line with the latest EU standards, not environmentally friendly): to visually determine the humidity from the color change. The principle is based on the principle of color change of the substance produced by the absorption of cobalt chloride.
The humidity card is reversible, the humidity exceeds the corresponding humidity value, the color changes from blue to red. If the humidity is lower than the corresponding humidity value, the already pinked humidity card can change back to blue, but only changes from pink to blue. The color takes longer and requires more desiccant to bring the humidity card back to blue.
The cobalt-free humidity indicator card is a convenient and inexpensive method for detecting the humidity of the environment. The user can quickly judge the humidity and desiccant effect in the product package by the color on the card. If the humidity in the package exceeds or equals the humidity value, the corresponding point on the card changes from a dry color to a hygroscopic color, whereby the use effect of the desiccant can be easily obtained.
