The 28878 is a replacement humidity indicator card. It provides a visual reference of humidity level inside the enclosure. Colored circles change color from blue to pink to indicate levels of 30%, 40%, and 50% relative humidity. Double sticky tape on the back of the card allows it to be easily secured to an enclosure lid.
