Jiuquan Satellite Launch Center (formerly the 20th base of the General Equipment Department) is the earliest and largest satellite launch center established in ChinaThe largest comprehensive satellite launch center is the main base for testing and launching Long March series carrier rockets, various experimental satellites in medium and low orbits, application satellites, manned spacecraft, and rockets. The base is also responsible for debris recovery, emergency rescue of astronauts, and other tasks. Since its establishment on October 20, 1958, the center has carried out 110 space launch missions, successfully sending 145 satellites, 11 spacecraft, and 11 astronauts into space.

Whether it is solid fuel or liquid fuel, the exhaust gas from propellant combustion during rocket operation will contain harmful gases such as sulfur oxides, nitrogen oxides, fluorides, etc. that can pollute the atmosphere.

So it is necessary to monitor and analyze the exhaust emissions after rocket launch. The leaders of Jiuquan Satellite Launch Center, after inspecting numerous enterprises engaged in gas analysis instrument research and development and production in China, chose the NK-800 series nitrogen oxide online analysis system from Xi'an Nuoke Instrument among many suppliers.

Faced with the requirements of aerospace grade, the people of Nuoke dare not slack off at all. Under the leadership of the chief technical engineer, after layers of technical research and development, our nitrogen oxide analyzer system parameters, performance and a series of technical indicators meet the requirements of the leaders of Jiuquan Satellite Launch Center, and stand out among many competitors.
