    • Metallurgy: Optimizes blast furnace and converter operations by analyzing CO, CO₂, and SO₂ levels.
  • Environmental Monitoring:
    • Air Quality Control: Detects SO₂, NOx, and particulate matter in industrial stacks to comply with emissions regulations.
    • Waste Incineration: Monitors harmful gases (e.g., dioxins, HCl) in incinerator flue gas.
  • Energy Sector:
    • Biomass Power Plants: Ensures optimal combustion by analyzing O₂ and CO levels.
    • Natural Gas Processing: Detects impurities like H₂S in gas pipelines.
  • Other Applications:
    • Cement Production: Monitors CO₂ in kiln exhaust for process optimization.
    • Food & Beverage: Verifies gas purity in modified atmosphere packaging (MAP).
    • Pharmaceuticals: Ensures inert gas quality in sterile manufacturing environments.

4. Key Advantages

  • Multi-Gas Capability: Simultaneously measures up to four gas components, reducing the need for multiple analyzers.
  • Low Maintenance: Self-cleaning sample chamber and automatic calibration minimize downtime.
  • Scalability: Easily integrates with existing control systems via RS-232/RS-485, Ethernet/IP, Profinet, and Modbus.
  • Cost-Efficiency: Reduces operational costs through improved process control and reduced emissions.
  • Global Support: Backed by ABB’s global service network for spare parts and technical assistance.

5. Certifications
