About

The Tri Gas Analyzer Model ATS-203A is a high-precision portable gas analyzer designed for accurate measurement of hydrogen purity using a three-gas measurement principle. It enables monitoring of H in air, H in CO, and CO in air, making it ideal for turbine generators and hydrogen-cooled systems. Utilizing a temperature-compensated thermal conductivity (TCD) sensor, the analyzer ensures fast response, high accuracy, and long-term stability. Its portable design, inbuilt sampling system, and rechargeable battery make it perfect for field use, purging operations, and industrial gas analysis applications.
