For continuous analysis of Sulfur Dioxide (SO₂) in process gas streams using an infrared detector. Percent and PPM levels available as Models 460 & 460L respectively.

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 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.
