8% Spot Match Reversible Humidity Indicator Card
This color-change Humidity Indicator Card was designed for use in desiccant containers in order to ensure that the desiccant is in an activated condition. It is fully reversible. A pink spot indicates a desiccant failure. A blue color reference bar is printed at the bottom of the card as a guide. When a container of desiccant is opened, the spot will match the bar if the desiccant is active.
NOTE: Humidity range is not indicated on this card.
