Combined Reversible and Irreversible Humidity Indicator Card MXC56789
The Maximum Humidity Indicator records relative humidity from 50 to 90% in 10% increments. The indicators are blue crystals which dissolve when exposed to the rated RH for 24 or more hours. The highest percentage spot containing dissolved solids indicates the maximum humidity reached.
The Reversible Indicator strip shows the current humidity (10 to 100%) when the package is opened, in the event that humidity rose and dropped during shipping. Read the strip at lavender between pink and blue for the current humidity.
