Nanjing Fourth Analytical Instrument Co., Ltd., formerly known as Nanjing Fourth Analytical Instrument Factory, was founded in 1976. It is the first manufacturer of high-speed analytical instruments in China, the founder of China's non-contact arc furnace, the standard drafting unit for detecting carbon and sulfur by arc combustion method, a promotion enterprise for the professional production of high-speed analytical instruments supported by the Ministry of Railways, the Iron and Steel Research Institute of the Ministry of Metallurgy, and the Jiangsu Machinery Industry Department. It is also a member unit of the Jiangsu Analysis and Testing Association, which represents the field of high-speed analysis. It is a member unit of the Shandong Foundry Association, Zhejiang Foundry Association, Precision Casting Association, and the East China Foundry Association. It is a member unit of China Quality Integrity Enterprise, Jiangsu Quality Integrity AAA level brand enterprise, and ISO9001:2008 international quality management system certification enterprise. Ning Sifan "Company is a specialized company that designs and manufactures high-speed analytical instruments on its own, and has formed strong alliances with universities such as" Southeast University "and" University of Aeronautics and Astronautics ". Over the years, the company has relied on its long production history, strong technical strength, excellent processing equipment, advanced production technology, high-precision testing methods, and has always adhered to the business philosophy of" honesty and hospitality, people-oriented, technology driven enterprise development, and innovation ". It seizes the market externally, excavates potential internally, strictly operates in accordance with the" Company Law ", and operates in accordance with the ISO9000 quality system standards. It continuously develops high-speed analytical instruments with excellent production performance, superior quality, and advanced domestic level. Its products have obtained multiple national patent certificates and are widely used in metallurgy, casting, mining, construction, machinery, electronics, environmental protection, health, chemical industry, power, technical supervision and other departments. They can detect the content of various chemical components in various materials such as steel, iron and iron alloys, aluminum alloys, copper alloys, zinc alloys, tin, lead alloys, pre-treatment solutions, plating solutions, steel oxidation solutions and phosphating solutions. Among them, the detection speed of carbon, sulfur, manganese, phosphorus, silicon, chromium, copper, nickel, molybdenum, titanium, vanadium, total rare earth content, magnesium, tungsten, cobalt, boron, arsenic, nitrogen, iron has been greatly improved compared with traditional methods. The detection speed of conventional furnace control elements has reached the level of The level of 'reading seconds'.
