About

The Online Tri Gas Analyzer Model ATS-208A is a high-precision industrial gas analyzer designed for continuous monitoring of three key gases in process and turbine applications. It enables accurate real-time measurement of gases such as hydrogen (H), carbon dioxide (CO), and oxygen (O) using advanced thermal conductivity, NDIR, and electrochemical sensing technologies. Engineered for online fixed installation, the analyzer provides fast response (T90 < 10 seconds), high accuracy (1% FS), and stable long-term performance. With its integrated sample conditioning system, flameproof design, and digital communication interfaces, it is ideal for hydrogen purity monitoring, generator safety, and industrial process control.
