Our humidity indicator cards, each packed with 10 cards, measure relative humidity levels in a contained environment by placing them in specific areas and waiting for the indicator dots to turn blue.
Use our humidity indicator cards to determine the humidity levels (or relative humidity, “RH”) in a contained environment.

Simply place a single card in the area to be read and wait for the indicator dots to turn bright blue in order to determine the humidity levels in that area.
