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 heat treat atmosphere gases such as Oxygen (O₂), Methane (CH₄), Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen (H₂), Ammonia (NH₃), and Dew Point (standard and low ranges). Also available for other industrial process gases.

Continuous analysis of flue gas for any combination and range of O₂, CO, CO₂, SO₂, NOx (NO or NO + NO₂) or combustibles from combustion processes.

For continuous analysis of many binary gas mixtures comprised of H₂, CO₂, O₂, CH₄, SO₂, Ar, He, NH₃, SF₆, air, and others. Applications include heat treating atmospheres, welding gas mixtures, blanketing gas mixtures, Ammonia synthesis, leak detection, purge monitoring, flue gas, magnesium blanketing by SF₆ and others.

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).
