The humidity indicator offers a quick and inexpensive method of checking the relative humidity in a warehouse or exhibition space.
As the humidity changes, the chemically impregnated spots change from blue (higher humidity) to pink (lower humidity). The humidity card indicates the current humidity on the lavender-colored section (between pink and blue).
The indicator has a scale of 6.
