## Description

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. The humidity card itself is reusable. When the humidity level is low, the dots will change from pink to blue again. With long use, the color of the dots may faint. Then, you can replace the card. DRY & DRY - PREMIUM QUALITY Our Humidity Indicator Card is the highest quality in the industry for Humidity Measurement. It is strictly tested for clear color change in each Humidity Level(10%-60%) You can experience a big difference compared to other products. Products of Dry&Dry guarantees 100% satisfaction. If you have any problems about our products, we will give you a free replacement or full refund.

Review: Etwas schlecht zu erkennen der Farbwechsel.
Review: I have a host of 3D filament spools and like to store them all in dry storage boxes, some are used infrequently and I'll store unopened spools as well. I bought the cheap $2 humidity sensors but they won't register below 20% and can't be used for really dry environments. These moisture indicating strips are cheaper and more accurate. They are really designed for dry storage measurements. The only downside is they are hard to read and it takes some "practice" to translate the lavender color to moisture value. I initially used a lab grade sensor as a reference and added it to some boxes with a strip to help me understand the color shift. I'm used to seeing the mostly blue dots and can pretty easily tell when the desiccant needs to be recharged. These are much better at monitoring dry storage than the cheapo humidity gages and I highly recommend.

## Questions & Answers

**Q: What does "can be reused 20x" mean if they don't require recharging?**
A: Yes sometimes you don't need to recharge it. Rainy days go to pink, sunny days go to blue again. If you change humidity level lower, they can go back to blue again. You can use hair dryer or sunlight to lower humidity level. Thank you.

**Q: What country are these manufactured in?**
A: They are manufactured in South Korea.

**Q: Are they safe to use in food containers?**
A: No they are not safe for food. Thank you.

**Q: Hi, are these cobalt-dichloride or cobalt-chloride free? when do they expire?**
A: Blue to pink humidity indicator cards contain cobalt chloride.  There's no expiration date on humidity indicator cards.  As long as you keep them in tight sealed container with silica gel packet, they will last for long time.  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. 
The humidity card itself is reusable. When the humidity level is high, the dots will change from blue to pink and when the humidity level is low, the dots will change from pink to blue again.  With long use, the color of the dots may fade away.  Then, you can replace the card.
We do carry cobalt free humidity indicator cards (green to purple). You type ASIN B01DYOR0WY in Amazon search bar.  Color change is not as clear as blue to pink (cobalt chloride) cards.  
Thank you.

I understood this product to be able to change colour back multiple times. However when I removed it from its packaging all dots turned pink and never returned back to blue again.
