English The QGO20 is an oxygen sensor designed for acquiring the residual oxygen content of flue gases in heat generation plant burning natural gas or light fuel oil. Together with the control unit, the QGO20 monitors and controls the combustion process. In conjunction with the LMV52 automatic burner control units for residual oxygen control, combustion efficiency is improved and pollutant emissions are minimized. Can be used for flue gas temperatures of max. 300 °C at the measuring point.
