What does a combustion analyzer measure?

A combustion analyzer measures the efficiency of fuel combustion and the emissions produced by heating appliances. This tool provides crucial data regarding the combustion process, including the levels of oxygen, carbon monoxide, carbon dioxide, and excess air. By assessing these factors, the analyzer helps technicians evaluate how well a heating system is operating and whether it is achieving optimal fuel efficiency.

Understanding combustion efficiency is important because it directly impacts energy consumption, cost, and environmental compliance. Properly tuned heating appliances will not only function efficiently but will also minimize harmful emissions that can contribute to air pollution.

In contrast, wall surface temperature is not a function of a combustion analyzer, nor does it provide insights into air pressure within duct systems or humidity levels. These factors pertain to different measurement tools and applications in HVAC and indoor air quality management.
