Humidity Indicator Card - 6 Spot, Reversible - 100pcs
10% 20% 30% 40% 50% 60% RHSKU: HIC6-100
Humidity indicator cards are paper instruments designed to monitor relative humidity in a sealed environment. These 6 spot cards are reversible and indicate relative humidity as low as 10% and as high as 60%. Spots change from blue to pink.
Humidity indicator cards provide a simple, reliable, visual indication of the relative humidity within a sealed environment. As the humidity increases, the spots on the card change from blue (dry), through to lavender, to pink (humid).
While they are not precision indicators, they are useful for quickly determining if an environment has exceeded a particular humidity threshold. For example, if all of the spots are pink on a 10-60% card, then the humidity in the environment has exceeded 60% RH. If all the spots are blue, then the humidity is still 10% or below.
It is recommended that the card is not placed in direct contact with metal objects as the chemical indicator in the card may cause corrosion of some metals.
