Product Introduction:

According to the national regulations issued by relevant departmentsexecuteStandard, our company has successfully developed itGC-7900R Natural Gas Online Analyzer,comply withGB/T13610-2003Gas Chromatography for Composition Analysis of Natural GasSH/T0230-92The national analytical and testing implementation standards required by the "Liquefied Petroleum Gas Composition Determination Method (Chromatography Method)" and others. Widely used in gas companiesAluminum manufacturing, thermal power plants, ceramics, metallurgy, glass, papermakingWaiting for natural gas user units to analyze and test the calorific value of the natural gas used.
GC-7900R Natural Gas Online AnalyzerIt can be directly connected to natural gas pipelines to achieve online injection analysis, and the analysis results can be obtained in about 10 minutes. And it can achieve 24-hour continuous online monitoring, and the analyzed data results can be uploaded to the central control system through the user's network platform protocol. Providing users with accurate, fast, and concise detection methods, making the analysis and monitoring data clear at a glance.
GC-7900R Natural Gas Online Analyzer is suitable forThe component content analysis and detection of pipeline gases such as natural gas, liquefied gas, liquefied mixed air, and gas distribution. The instrument's built-in analysis software system can calculate characteristic indices such as high calorific value, low calorific value, density, relative density, Huabai number, and combustion potential of different gases in seconds.
GC-7900R Natural Gas Online AnalyzerFull analysis of oxygen, nitrogen, methane, ethane, propane, isobutane, n-butane, n-pentane, isopentane, and hydrocarbons with C6+or higher in natural gas can be performed in one injection.

Key Features:
