Integra Humidity Indicators
Humidity indicator cards are simply cards that have a dot on them that will turn a color to indicate when it’s time to replace your humidity-control pack. When the dot on the back turns bright blue, that’s your indication that the current pack has used up all of its contents and that it’s time for a fresh BOOST pack.
Benefits + Features:
- Accurate way to check the vitality of your pack!
- Indicates how well your pack is!
- Simple to use! (Place a single card in the area to read and wait for the indicator dots to turn blue)!
