Mr. Wang weijian, chairman of the company, introduced the development of the medical technology in recent years and the environmental protection management of ahwa.

In terms of environmental protection treatment, the company has increased its investment in environmental protection. In 2015, the company invested more than 4 million yuan in upgrading and upgrading of waste water treatment, recycling waste water and realizing zero waste water discharge.

The ministry of environmental protection and provincial, municipal and county leaders visited the company's temperature-sensing and electronic product production lines, and watched the production process in detail.

With the implementation of the international minamata convention, mercury thermometers are about to exit the stage of temperature measurement. Faced with serious situation, the company began to develop the replacement product--gallium indium tin thermometer from 2006. As an alternative to the product containing mercury thermometer, the production technology of gallium indium tin thermometer has been mature. The accuracy, stability and performance of the mercury thermometer are consistent, and is safer than the mercury thermometer. There is no need to worry about the environmental pollution caused by product breaking.

The leaders of the ministry of environmental protection gave full recognition to the company's products and environmental protection work, and proposed to follow the international environmental development trend and speed up the popularization of mercury-free products.
