Products > Process > Laser Gas Analyzer > LGA - 4500

Features and Benefits

  • Fast response

  • High accuracy, ppm level resolution

  • No cross interference

  • Online calibration, no zero drift

  • Reliable in all harsh conditions: high temperature &

    pressure, dust density, moisture and corrosion

  • International ATEX certified


Application Areas

  • All other applications where in-situ doesn’t fit due

    to high pressure or dust density, limitation of stack

    diameter or position.

  • HCL, HF, NH3 , H2S emission monitoring

  • Trace H2O in VCM Production

  • Coal Injection Safety Control

  • SCR NH3 Injection in Coal-fueled Plants
