KGD - MQ - 514 Combustion Efficiency Analyzer for Industrial Sites
Product Introduction
The KGD - MQ - 514 Combustion Efficiency Analyzer adopts non - dispersive infrared (NDIR) gas analysis technology with independent intellectual property rights and long - life electrochemical sensing technology. It can simultaneously measure the volume concentrations of gases such as CO, CO₂, and O₂, as well as the flue gas temperature, and calculate the excess air coefficient, providing a basis for adjusting the combustion conditions in industrial sites.
