The technological innovation project of the Chongqing Sichuan Instrument Factory has achieved remarkable progress. The "PA200 Series Intelligent Gas Analyzer," developed by the company, has successfully passed the expert evaluation organized by the Chongqing Municipal Science and Technology Commission. This achievement marks a significant milestone in the company's R&D efforts, as several products have reached new technical heights and received high praise from the expert panel. During the evaluation process, the expert team carefully reviewed the technical reports submitted by the factory’s research team, examined the project documentation, and conducted an on-site inspection. They also participated in a detailed defense session. After thorough discussion and analysis, the experts confirmed that the "PA200 Series Intelligent Gas Analyzers" are capable of real-time online analysis and accurate quantitative detection of various gases, such as SO₂, NO, O₂, CO₂, CO, CH₄, and NH₃, commonly found in industrial processes. Among the series, the "PA200-GXH Intelligent Infrared Gas Analyzer" stands out for its advanced infrared technology in detecting SO₂ and NO, filling a critical gap in domestic gas analysis solutions. Additionally, the "PA200-CY Intelligent Magnetic Pressure Oxygen Analyzer" and the "PA200-CJ Intelligent Magnetic Oxygen Analyzer" represent exclusive domestic production with a high level of intelligence and accuracy in oxygen measurement. These PA200 series instruments not only meet the growing demands in environmental monitoring, quality control, and industrial safety but also significantly enhance the smart capabilities of analytical equipment in enterprises. This success highlights the factory's effective implementation of its technological innovation strategy and demonstrates its strong potential to lead in the field of intelligent gas analysis.
