In high humidity environment, semi-conductor, electronic instrument and spare parts are possible to be damaged by moisture in the air.
Humi-Watch®HIC(Humidity Indicator Card) is a kind of environmental measurement product to test the safety of related humidity in the sealed package.
Our Humi-Watch® will be helpful in judging if the package is safe to the product, indicating if the desiccant inside the package remains valid or needs to be replaced. The humidity indicator dots will change from blue to pink as the relative humidity increases in the volume of air surrounding the indicator. The humidity indicator dots are reversible, and the pink dots will change back to blue when the volume of air is dried. So, when open the package or container, if the humidity indicator dots are blue, it shows that the product is well sealed and in safe conditions.
Humi-Watch® is a necessary product to the safe sealing package.

The inner package is PE bag and round metal pot, the outer package is paperboard carton, 10pot/carton Carton size: 430*175*130mm / 430*175*100mm(two kinds)
Humi-Watch® should be sealed in metal pots with desiccant. Desiccant should be replaced after the metal pots being opened for 3 times.
Store Humi-Watch® in dry and cool environment and prevent it from sunshine and moisture
In 1998, the European Community (EC) issued the directive (67/548/EEC) on its 25th council concerning the adaptation to technical progress, on which the cobalt chloride was lined into one of the dangerous substances possibly causing cancer. Though the EC issued it, it was not forbidden formally.
With the technology improvement, people has more concerns of health and safety and higher requirements of environmental protection. Most of the integrated circuit manufacturers agreed that if the traditional humidity indicating method may cause cancer, then it is not applicable, and it shall be eventually replaced by Cobalt-free product.
Then the EC environmental regulation 2004/73/EC came into force, in which cobalt dichloride is listed as a banned material for using.
After several years of effort, TOPSORB has developed Humi-Watch+, a new generation of humidity indicator card (HIC), which is cobalt-free humidity indicating card of high precision, adapting to the new EC standard.
Humi-Watch+(Cobalt-Free)
Up to now, most domestic suppliers of humidity indicating card in China are using burette by hand to drop the solution onto the cards. It is very rough and inefficient with unqualified products at high percentage. It is hard to control the strength precisely by hand when dropping. If no enough dropping, it will not cover full inside the circle print. If too much dropping, it will overflow the circle print.
We produce humidity indicating card by automatic machine. Our production efficiency is ten times to hand dropping. What is more, the size and strength of dropping is very precise, perfectly fitting the print circle. It has absolutely overcome the difficulties of uncontrollability of hand dropping.
