Integra Humidity Indicator Cards 10 Pack

Use the Integra humidity indicator cards to determine the humidity levels (or relative humidity, often referred to as “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.
