Oxygen analyzers are used to measure the quantity of oxygen in air or in other mixtures of gases, such as exhaust flue gas from a process. Oxygen, along with nitrogen and hydrogen, is a major component of air making up 20.9% of the air we breath. Oxygen is also used in the industrial combustion process, and when fuel is burned in presence of oxygen, CO, CO2, and H2O are by-products of that combustion. By measuring the oxygen in combustion process the proper air-to-fuel ratio can be maintained for optimized process efficiency.
Oxygen analyzers are used to determine exhaust gas concentration of oxygen in many applications from internal combustion engines to combustion applications in industrial plants. Many industries such as powergen, refineries, chemical plants, cement plants, asphalt production, and agrochemicals all require oxygen measurement.
