JNYQ-S-81 flue gas analyzer

Introduction:

   JNYQ-S-81 flue gas analyzer is a gas analyzer product independently developed for on-line gas analysis of environmental protection and industrial control at home and abroad. The analyzer is based on the principle of ultraviolet absorption spectroscopy and can measure the concentration of SO2, NO, NO2, O2 and other gases. It has the characteristics of high measurement accuracy, high reliability, fast response time, and wide application range. It can be widely used in online environmental monitoring , Industrial control, safety monitoring and other occasions.

Application areas:

Continuous monitoring of CEMS for flue gas emissions of power plants (analysis of SO2, NO, NO2, O2)

Desulfurization process monitoring (analysis of SO2, O2)

Denitration process monitoring (analysis of NO, NO2, NH3, O2)

Continuous monitoring of waste incineration flue gas emissions (analysis of SO2, NO, NO2, O2)

Chlor-alkali plant PVC process and titanium dioxide production process trace Cl2 analysis (Cl2 analysis)

Sulfur recovery process gas analysis (analysis of SO2, H2S)

Natural gas purification process gas analysis (analysis of trace H2S)

Coal chemical industry methyl iodide analysis (analysis of CH3I)

Atmosphere online monitoring (analysis of SO2, NO2, O3), etc.
