Description:

The MG8G paramagnetic oxygen analyzer measures the concentration of oxygen based on the fact that a magnet attracts gaseous oxygen. Whereas zirconia oxygen analyzers cannot measure oxygen in flammable gas mixtures, the MG8G can measure oxygen concentration in flammable gas mixtures. With an appropriate sampling system it can also measure oxygen in high temperature, high pressure, high dusty, or high-humidity process gas mixtures. The sensor has a totally new architecture for its magnetic proportional flow rate system that has been developed based on our long and field-proven experience. The converter provides ease of use and high reliability.……
