JES-9100FIR Portable Fourier Transform Infrared Spectroscopy Gas Analyzer

JES-9100FIR is a portable Fourier transform infrared spectroscopy gas analyzer independently developed by Le Shi Technology. It uses full spectrum analysis technology (FTIR), and one analyzer can test all substances with absorption in the infrared spectrum range. Therefore, JES-9100FIR can test thousands of gas types.

The portable Fourier transform infrared spectroscopy gas analyzer is mainly used for monitoring fixed pollution source exhaust emissions and precise qualitative and quantitative detection of organic and inorganic gases in ambient air, achieving real-time emission monitoring of pollution sources, detection of sudden environmental pollution accidents, and rapid qualitative and quantitative analysis of gases in environmental air monitoring and detection. It has been widely used and recognized in the fields of industrial waste gas, boiler flue gas, incinerator emissions, engine exhaust (vehicle/ship/aviation), CEMS comparison, catalytic reduction performance monitoring, gas purity analysis, and scientific research.

Capable of precise detection simultaneously SO2、NO、NO2、CO、CO2、NH3、HCL、HCN、HF、H2O、 CO2、N2O、CH4、C2H6、C3H8、C2H4、HCHO、C6H6、C7H8、C8H8、C8H10、 C2H2 Wait for no less than 51 gas concentrations and no less than 380 qualitative and semi quantitative components.

One machine for multiple purposes: truly realizing that one device can be used in multiple scenarios for on-site monitoring of fixed pollution sources and emergency detection of environmental air. Different models can be built for different working conditions to improve equipment utilization and practical value.
