Hefei Qingxin Sensing Technology Co., Ltd. (hereinafter referred to as "Qingxin Sensing") is a high-tech enterprise mainly engaged in the research and development, production, sales, and service of gas sensors.
Clear core sensing focuses on major strategic needs such as national urban public safety, aiming for cutting-edge technology in the field of gas detection laser detection. It has successfully developed a series of methane and other gas detection laser chips and modules with independent intellectual property rights. They were released globally at the opening ceremony of the World Manufacturing Conference in September 2022, marking the beginning of the localization of the gas detection laser era.
Clear core sensing has deeply promoted the industrialization and large-scale application of scientific research achievements, and has actively expanded the application scenarios of combustible gas laser detection chips and sensors in conjunction with leading enterprises in the field of urban safety such as Chen'an Technology and Science and Technology University Li'an. The products have been applied in over 250000 sets of urban lifeline projects in Anhui, Tianjin, Urumqi, Chengdu and other places. While effectively ensuring the safe operation of important urban infrastructure, the company's reputation and influence have been rapidly improved, forming a good development momentum of both quantity and quality, and steady growth.
Qingxin Sensing will always bear in mind its corporate mission of "safeguarding urban safety with technological support", and is committed to promoting the healthy development of the sensor and IoT industries with a spirit of exploration and innovation. We will continue to use advanced sensor technology to create a safe, environmentally friendly, healthy, and intelligent production and living environment.
