Description: Flue Gas Oxygen Analyser, Model ACE 200-Zirconia is designed to measure oxygen concentration in the flue gas from the combustion processes. Each analyser includes oxygen sensing probe, protective support shield, 6 meter cable, electronics package, reference air set and calibration gas rotameter in-built adaptor plate and accessories. The heart of the systems is the Zirconia sensor, which when maintained at elevated temperature gives an output (based on Nernst equation), which is a function of the gas constant, the absolute temperature, Faraday's constant, the natural logarithm of the rate of the partial pressure of oxygen on the two dies of the cell. This means if the temperature is held constant and air (20.9% oxygen) is used as reference air, the output becomes the inverse logarithm of the partial pressure of oxygen in the measured gas.
