Brief introduction of Henan Han Wei Electronics Co., Ltd.

Henan Han Wei Electronics Co., Ltd. (stock code: 300007) now has a relatively complete production technology of gas sensors, detection and alarm products, and has formed a series of nearly 50 varieties and specifications such as sintered semiconductors, catalytic combustion, hot-wire gas sensors and gas detection instruments. Sensors and alarm products can detect flammable gases such as hydrogen, liquefied gas, natural gas (methane), butane, propane, carbon monoxide, alcohol, acetone, gasoline and liquid vapor, as well as toxic gases such as ammonia, hydrogen sulfide and nitrogen oxides, as well as carbon dioxide and ozone gas, which are widely used in industrial fields such as petroleum, chemical industry, metallurgy, mining, pharmacy, painting booth, home, shopping mall, liquefied gas station, gas station and so on.

The gas detection products of Henan Han Wei Electronics Co., Ltd. adopt many new sensor technologies and original circuit designs, which are innovative and high in technology. Many technologies have passed the provincial appraisal and won awards, and many products have obtained the model approval of fire protection products and the manufacturing license of measuring instruments. The comprehensive technical level is in a leading position in the same industry in China, enjoying a high reputation and wide popularity, and successfully entering the international market.

The company has its own R&D center for gas sensors and R&D center for electronic products, with complete testing methods and emphasis on scientific research and development and academic exchanges. With Tsinghua University, Shanghai University, Xi Jiaotong University, Wuhan University of Technology, Zhengzhou Institute of Light Industry, Institute of Physics of Chinese Academy of Sciences and many other universities and research institutions, we have established long-term and extensive cooperative relations and enjoyed a high reputation in the gas sensing academic circles. Henan Han Wei Electronics Co., Ltd. is a group member and deputy director of the National Gas Sensing Professional Committee and a member of the National Sensitive Components Industry Association.

The company advocates the corporate culture of people-oriented and technological innovation. While constantly improving existing products, we attach great importance to the development of new products, and more and more new varieties are constantly introduced and put on the market.

Providing the most suitable gas detection solution is our goal, and the satisfaction of users is our pursuit!
