Chengdu Region Technology Co., Ltd

3 Dots Cobalt Dichloride Free Humidity Indicator Card

Humidity indicator cards are used in sealed packaging of high-grade electronic components and instrumentation (e.g. integrated circuits, ICs, chips, etc.) that are sensitive to humidity. when the improvement of environmental requirements in the industry, environmentally humidity indicator cards without cobalt dichloride are produced.

Cobalt dichloride-free humidity indicator cards are used to show relative humidity in enclosed spaces.  it cannot approach liquid water. Indicates that the colors within the dot vary with humidity, that the color changes in the dry and wet states of different products are easy to identify, and that the indicator values are stable and reusable.

Description

Humidity indicator cards are used in sealed packaging of high-grade electronic components and instrumentation (e.g. integrated circuits, ICs, chips, etc.) that are sensitive to humidity. when the improvement of environmental requirements in the industry, environmentally humidity indicator cards without cobalt dichloride are produced.

Cobalt dichloride-free humidity indicator cards are used to show relative humidity in enclosed spaces. it cannot approach liquid water. Indicates that the colors within the dot vary with humidity, that the color changes in the dry and wet states of different products are easy to identify, and that the indicator values are stable and reusable.

Instructions for use

1. Humidity means that the color of the stuck point will sense the relative humidity of the environment in a certain confined space, and change from a dry color to a corresponding wet color.
2. The relative humidity value corresponding to each point is printed next to the display point.
3. Humidity means that the relative humidity of the card changes during the exposure process, and the color will change.
4. When a certain amount of air is dry, the humidity indicates that the color of the stuck point changes from wet to dry. Put the humidity indicator card into a sealed container with an appropriate amount of desiccant, and turn it from wet to dry.
5. Humidity means the stickiness is dry before use.
6. Humidity indicates that the humidity displayed at 23 degrees Celsius is the most accurate.
7. Do not touch the indication points, and do not wash any display area with water.

Product storage

1. The product is sealed and stored and must not be exposed to air for long periods. it must put in a dry and shady place.
2. Avoid direct sunlight. Stay away from places with high humidity such as sunlight and water

Precautions

Humidity card can not open the packaging humidity indicator card container for a long time. each time open to immediately seal, indicating that the card to be ready-to-use. when the humidity card is opened, the humidity indicator point should be dry color, if the color displayed and dry too color inconsistent, that proves that the packaging container is not sealed, it must need to dry to the dot to restore dry color can be used.
