DRY & DRY - OUR PRODUCTS Dry & Dry Humidity Indicator Card is Premium Quality. It is strictly tested for clear color change When you initially open the card, all dots sometimes react and change color because they are exposed to sudden humidity. If you wait for about 30 minutes, the card will calibrate and you will be able to read the humidity level. If 10% dot is pink and 30% dot is blue, and 20% dot is lavender, then the humidity level is about 15%. If the 30% dot is pink, it is time to change the desiccant.
