Why use humidity indicator cards?
Most electronic components, precision optical components and other products are easily affected by moisture, leading to corrosion, reduced sensitivity, damage, etc. To prevent products from being corroded and damaged by moisture, humidity indicator cards are monitoring instruments that monitor relative humidity (RH) levels in sealed environments.

Product Introduction
Special for humidity sensitive components
The humidity indicator card is a small paper instrument that can monitor the relative humidity level in a closed space. The percentage data above or on the side of the circle is the relative humidity data indicated by the corresponding circle. Humidity indicator cards are suitable for high-end electronics and instruments such as electronic components and precision optical components.

Product Features
High sensitivity and rapid judgment
The humidity indicator card is made through technological processing. The percentage data above the circle corresponds to the relative humidity indicated by the circle. The humidity indication is highly sensitive and can quickly determine the humidity value.
Large indication range, precise color change
The humidity indication range is large (10%-60%), and when the humidity around the humidity indication card rises to a certain value, the color of the corresponding circle on the indication card will change.
Color reversible, reusable
The color in the circle of the humidity indicator card is reversible. When the surrounding area of the humidity indicator card dries, the color in the circle will return to its original color. It has a long service life and can be reused after drying.
Canned packaging, easy to use
Keeping the instruction card sealed in a vacuum packaging jar and adding desiccant can not only better prevent air penetration, but also make it easy to use.
Complete specifications, support customization
Humidity indicator cards can be processed with customized sizes, humidity specifications, packaging material printing, etc. according to different application scenarios to meet various customization needs.

User manual
Instructions for use of humidity indicator card
Place the humidity display card in the sealed space where the surrounding humidity is to be tested
|
Check the color change of the corresponding humidity point to determine the humidity of the surrounding environment |
Take appropriate action based on indicated humidity conditions
|
1. When using the humidity indicator card, do not touch the indicator ring directly with your hands.
2. Please use according to the usage quantity and avoid long-term (30 seconds) exposure to the air. If it changes color before use, please dry it before use (it can be dried in a drying oven until it completely turns blue/ brown/yellow).
3. As the humidity of the surrounding environment increases, the indicator point on the humidity card will change from dry color to wet color.
4. The humidity card is a reversible card, that is, the wet color indicator point will change back to the dry color as the humidity of the surrounding environment decreases.
5. When the color of the indicator point changes to the specified color, the value of the point is the humidity value of the current environment.
Precautions
Precautions for storing humidity indicator cards
1. Please keep it sealed when not in use.
2. The humidity indicator card is sealed and stored in the packaging iron can, and desiccant is placed in it. Please replace the desiccant after the package is opened three times.
3. Store in a dry, cool environment, avoid direct sunlight and water immersion.
4. Please place it away from sunlight, water and high humidity and out of reach of children.
5. When the humidity in the environment becomes low, the color effect is reversible and you can continue to use it.
6. Depending on the quantity used, a small drying box can be used to ensure that the humidity indicator card is hot-packed during use. This can prevent the humidity indicator card from getting damp during use and ensure the quality of use.
7. Do not touch the indicator dots, and it is prohibited to clean any display area with water.
