  • Measured Components SO2, NO, NO2, NH3
    Measurement Principles Differential Optical Absorption Spectroscopy (DOAS)

    Measuring Ranges

    SO2: 0~50 / 0~100 / 0~200 / 0~500 / 0~1,000 / 0~2,000 ppm

    NOx: 0~40 / 0~100 / 0~150 / 0~200 / 0~500 / 0~1,000 / 0~2,000 ppm

    NH3: 0~10 / 0~20 / 0~50 ppm
    Min. Measuring Unit 0.1ppm

    Certificates / Approvals

    • Type Approval (Korea)

      Performance Approval (Korea)

      CPA, CCEP (China)

      TUV (Germany)

  • System Components

    • DGA-X Main Unit / Probe / Power Distribution Panel

      / Air Purge Unit / Master Flange / Cables

    DGA - X Features

    • Simultaneous measurements for two components among NOx, SO2, and NH3

      Less interenference from moisture and particles as it uses UV light source

      NOx converter is not required as it measures NO and NO2 separately

      Enclosure level up to IP66 and NEMA4X

      Real Gas Calibration using patented Auto Calibration Unit (ACU)

      EX version is available as an option
