Webinar: The Importance of CO/Combustion Testing


We all know that exposure to high levels of CO is extremely dangerous, and can even be deathly. Making it crucial to measure Carbon Monoxide and combustion levels in your surrounding area, especially when working around fuel-burning appliances or flue gas conditions. Given this, our mission is to provide HVAC technicians and contractors with a better understanding of the theories of combustion, CO safety standards, and environmental compliance in commercial and residential fuel-burning appliances. We can help!

Recently, we teamed up with Testo to host an informative webinar! We provide you with detailed combustion testing recommendations and OEM specifications on different types of burners to ascertain and to make the right measurements, to interpret these measurement results, and take corrective action to ensure safe and efficient operation of the combustion process. In addition, We’ll review the current and recommended standards for CO safety in ambient air and in flue gas conditions.

This webinar addresses the following issues:

  • Why is Testing CO/Combustion Important?
  • Basic Theories of Combustion & CO Safety
  • Recommended and Typical Test Results
  • Making Good Measurements of the Following Parameters...
    Net Temperature, Oxygen (O2), Carbon Monoxide (CO), Stack Draft, NOx, NO, NO2, SO2
  • Care & Service of Combustion Analyzers
  • New Testing Technologies (Testo 300)
