For continuous analysis of Carbon Dioxide (CO₂) in process gas streams using an infrared detector. Percent and PPM levels available as Models 420 & 420L respectively.

Designed for the continuous monitoring of O₂, CO, CO₂, and/or H₂ gases from blast furnaces or other continuous industrial processes where an uninterrupted stream of gas concentration data is critical. Calculated values of BTU, N₂ and efficiency are also available.

For continuous monitoring of any combination of gases such as oxygen (O2), methane (CH4), carbon dioxide (CO2), carbon monoxide (CO), and hydrogen (H2) for industrial processes including metal heat treating atmospheres.

For continuous monitoring of syngas and gasification atmospheres or other industrial process gases for any combination of methane (CH₄), carbon dioxide (CO₂), carbon monoxide (CO) and hydrogen (H₂) and oxygen (O ₂).

910 Series
