The most common measurement for the purposes of efficiency are oxygen (O) or carbon-dioxide (CO2) and temperature. For a given fuel type, it is possible to calculate the percent O if CO2 is measured, or to calculate CO2 if O is measured. Another common indicator is CO; if O is high, there won't be any significant CO.Get Price
