CEMS-4000 VOC is an online emission monitoring system based on catalytic oxidation-FID technology, which can monitor volatile organic compounds (including total hydrocarbons, non-methane total hydrocarbons, etc.) in the flue gas. The system supports multiple installation methods, including wall-mounted installation, platform installation, cabin-type installation, etc. It can be widely used in the oil and gas industry, electronics industry, automobile manufacturing industry, and pharmaceuticals industry.


  • Catalytic efficiency ≥98%, reaching international standards.
  • Complete heat tracing avoids sample loss.
  • Flexible installation: wall-mounted installation, platform installation, cabin installation
  • Measuring non-methane total hydrocarbons by catalytic oxidation-FID, with less pipe and valve parts and simple maintenance.
