For continuous analysis of up to 0-10000 PPM Carbon Monoxide (CO) in process gas streams using an electrochemical detector.

For continuous analysis of Carbon Monoxide (CO) in process gas streams using an infrared detector. Percent and PPM levels available as Models 481 and 481L respectively.

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.

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.
