(cobalt free Brown humidity indicator card)
* cobalt free humidity indicator card;
* specific color change to brown (dry) - > Blue (Shi Run);
* the color change of the indication point is reversible and can be reused;
* the percentage value after discoloration is natural humidity;
* specific specifications and humidity values can be formulated
1 product overview:
Humidity indicator card (Humidity Indicator) is a visual card, the user can change the color of the card through the card to quickly determine the product packaging environment humidity and desiccant use. The cards in each dot represent a humidity value, with the relative humidity values change from blue to pink gradually respectively, relative humidity can determine the environmental value, to help determine whether the need to replace the desiccant.
2 major application areas
* IC/ integrated / PCB packaging etc.
* food, medicine, storage, etc.
* electronic components packaging, optical equipment, sensitive components
* military products, aerospace products, precision machinery industry
* other moisture-proof products packaging
3 working principle:
The utility model is convenient and easy to use, and can be used for quick interpretation of humidity. When the indication point becomes pink, the value of the indication point is the current ambient humidity;
The color change of the indicator point is reversible, and when the air around the card becomes dry, the color of the indicator point changes from pink to blue;
Various specifications can be used in the relative humidity of 5% - 90% of the various occasions;
The humidity indicator is correct and the error is within 5%
4 packaging and preservation
The inner packing is a vacuum bag and a metal pot.
The humidity indicator card sealed in packaging cans, desiccant and packaging, opened after the three time please replace the desiccant.
Keep in a dry and cool environment, avoid direct sunlight and water immersion.
