Integra Boost – 1 PACK X 10 HUMIDITY INDICATORS CARD / Humidity paper test

Use our humidity indicator cards to determine the humidity levels (or relative humidity, "RH") in a contained environment.
Each pack contains 10 humidity-indicator cards, and each card will read RH from 10%-60%. 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.
