Five(5) 50-70-90% Reversible Relative Humidity Indicator Cards
Packaged in a re-closeable moisture barrier bag.

Reversible Relative Humidity Indicators are a quick and easy way to 'see' the humidity level within the enclosed space. Simply read the humidity level of the highest spot that is turning pink. The spots will continuously change as the humidity level changes.
The 50-70-90% RH Cards are for indicating higher moisture environments. If placed in an area where Dri-It is working, these cards should not indicate anything as Dri-It works to maintain about a 30% RH environment. You'll know it's time to replace the Dri-It pouches if the 50% starts to indicate.
