Deyang Kerui Instrument Equipment Factory is located in Dexin Industrial Park, Deyang City, on the western Sichuan Plain of China's industrial heavy equipment base, adjacent to Chengdu and Mianyang. It is a contract abiding and trustworthy enterprise in Deyang City, Sichuan Province, integrating industry, academia, and research, and a national high-tech enterprise (certificate number: GR201451000394). The company relies on the China Institute of Testing Technology as its technical support and forms an expert group for research and discussion. The members of the expert group are senior professors who have long worked in the fields of optics, electronics, chemistry, and computer science. They constantly improve and update their instrument products, specializing in the research, development, production, and promotion of high-frequency infrared carbon sulfur analyzers, X-ray fluorescence spectrometers, chromatographs, industrial analyzers, calorimeters, high-temperature sulfur analyzers, crushers, prototype machines, glassware, chemical reagents, and other related products. They are committed to the research of metallurgical technology application methods and the innovation of industrial analytical testing instrument technology. Establish a doctoral research and development center within the unit to continuously conduct product development and innovation. Technical Chief Engineer: Liu Weili has been engaged in carbon and sulfur analysis and testing for more than 50 years, and has been engaged in the development and production of carbon and sulfur meters for 23 years. He has accumulated rich experience in the development, analysis, and testing of carbon and sulfur meters. In 2007, the first infrared carbon analyzer in China capable of accurately detecting one microgram of carbon content was developed and produced, meeting the analysis requirements of the nuclear industry for carbon content in a certain special material. In 2013, a multifunctional infrared carbon and sulfur analyzer was successfully developed, breaking the current limitation of infrared carbon and sulfur analyzers that can only measure total carbon and total sulfur. The company has established a third-party cooperative laboratory with the Physical and Chemical Testing Center of Baotou Rare Earth Research Institute to share experimental samples, equipment usage methods, and performance parameters. The State Key Laboratory has used our high-frequency infrared carbon sulfur analyzer for a long time. The physical and chemical testing center of Baotou Rare Earth Research Institute (hereinafter referred to as the physical and chemical testing center) was founded in 1963 and was recognized as a national rare earth product import and export commodity inspection laboratory in 1987. Our factory has applied cutting-edge technological achievements to the development of high-frequency infrared carbon sulfur analyzers, becoming a leading manufacturer of carbon sulfur analysis instruments and receiving high praise from users for many years. In 2015, our company collaborated with Sichuan Engineering Vocational and Technical College to establish a key research and experimental base, continuously innovating and improving the technology and performance of equipment. In 2016, an agreement was reached with the Analysis and Testing Department of Kunming Metallurgical Research Institute to establish a joint laboratory and collaborate on the development of new methods for carbon and sulfur testing and analysis. In April 2016, Deyang Kerui was officially listed on the New Third Board of the Sichuan Tibet Equity Trading Center. The company has established offices in various parts of China, including Panzhihua, Kunming, Xi'an, Xining, Korla, Xinjiang, Ningxia, Baotou, Shenyang, Chongqing, Guizhou, Guangdong, etc. The COREY-200/100 series of high-frequency infrared carbon and sulfur analyzers have been developed and sold in more than 20 provinces, municipalities, and autonomous regions in China, and exported to Southeast Asia and Africa. Widely used in scientific research fields such as metallurgy, machinery, mining, commodity inspection, nuclear industry, coal, automobiles, ships, aerospace, building materials, universities, geology, petrochemicals, etc. Our series of high-frequency infrared carbon and sulfur analyzers were awarded seven national patent technologies in 2012, including dual brush high-pressure dust removal system (ZL 2011 2 0378012. x), isolated infrared detection cell (ZL 2011 2 0376950.6), passive constant current device (ZL 2011 2 0379930.4), infrared detection cell constant temperature system (ZL 2011 2 0377343.1), fully automatic intelligent sampling robot (ZL 2011 2 0572238.3), exhaust gas treatment device (ZL 2013 2 0218618.6), arc combustion chamber (ZL 2013 2 0012298.9), and HCS-KR200 high-frequency infrared carbon and sulfur analyzer (ZL 2013 3 0101530.1), DKR-1. Two design patents for the appearance of the 00 high-frequency plasma infrared carbon sulfur analyzer (ZL 2013 3 0101529.9). In 2016, four utility model patents were obtained, including an automatic dust removal device (ZL 2016 2 0328 070.4), a new electric heating device (ZL 2016 2 0125801.5), a furnace component (ZL 2016 2 0328205.7), and an analytical instrument structure with a lighting group (ZL2016 2 0125 802. X). The invention patent (a gas constant current and temperature system 201510586494.0) has passed the preliminary review The leading product quality has been unanimously recognized by a large number of users.
