Humidity indicator card manufacturer customized 6-point humidity card environmental protection
Humidity indicator card is a convenient and cheap method to detect environmental humidity. The user can quickly judge the temperature inside the product package and the effect of desiccant by the color on the card. If the humidity of the package is higher than or equal to the humidity value, the corresponding point on the card will change from dry color to extremely wet color, thus the use effect of desiccant can be easily known.
In 2004, the EU environmental protection regulation (2004 / 73 / EC) has listed cobalt oxide as a class II carcinogen, which is now prohibited by cobalt humidity indicator card. All products exported to EU countries must comply with the regulation. Therefore, the widely used humidity indicator card (from blue to pink), the main component of which is cobalt oxide, will soon be banned.
In order to meet the relevant regulations and environmental protection requirements, neume Electronic Materials Co., Ltd. has developed a new generation of environmental protection humidity indicator card (type I, II, III), and has upgraded the production process of the indicator card at a higher level. This series of products comply with the European Union RoHS Directive (not included), has passed the CTI / SGS test, indicating that the color change is obvious, the workmanship is excellent, and the use is convenient.

Jeoec (electronic components industry federation standard)
Scope of application
Packaging of electronic components, optical equipment, sensitive components
All kinds of vacuum packaging
IC / integrated / circuit board, etc
When the humidity of the environment reaches or the value of the indication point on the humidity indicator card, the indication point changes from dry color to hygroscopic color.
When the humidity of the environment decreases, the color of the points on the indicator card will change from hygroscopic color to dry color.
When the color of the indication point changes to the specified color, the value in the point is the humidity value of the current environment.
And can be customized according to customer requirements and special needs.
Packaging and storage
1. The inner packing is sealed bag and outer metal tinplate, and the outer packing is carton, 2400pcs / box / 5 cans
2. The humidity indicator card should be sealed in the iron can with desiccant. Please replace the desiccant after the package is opened three times.
3. Keep in dry and cool environment, avoid direct sunlight and water immersion.
