- Card Dimension : 1.5"(3.8cm) x 4.5"(11.5cm). Humidity indicator cards are sensitive to temperature, humidity, atmospheric pressure, and wind. Therefore, they do not work well in open air. They work well and display accurate relative humidity level in enclosed space.

- CONTINUOUSLY & ACCURATELY Displays Humidity Level - If the humidity level becomes lower, the strip will change back to Green (the original color). Just because the color has changed to the next level does not mean it cannot go back to the previous color. The colors will change depending on the humidity level.

DRY & DRY - OUR PRODUCTS
•Dry & Dry Humidity Indicator Card is Cobalt Chloride Free.
•It is strictly tested for clear color change
•It is Eco Friendly.
•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 Purple and 30% dot is Green, and 20% dot is Gray, then the humidity level is about 15%. If the 30% dot is Purple, it is time to change the desiccant. The humidity card itself is reusable. When the humidity level is low, the dots will change from Purple to Green again. With long use, the color of the dots may faint. Then, you can replace the card.
