Choosing an HVAC Combustion Analyzer

When heating and cooling professionals call on a Hvac combustion analyzer to help them diagnose an issue or troubleshoot a problem, they want a quality tool that will quickly and accurately show them the state of the equipment. They’re looking for a tool that can measure ambient CO concentration, the fuel type and amount being burned, the appliance combustor’s temperature and efficiency, and more. These tools also serve to ensure a space from essential community spaces to classrooms is heating properly and reducing the risk of carbon monoxide poisoning.

What is the difference between commercial and residential combustion analyzer?

When choosing a new commercial combustion analyzer, HVAC pros need to take several factors into account including regulatory emission requirements, the budget they’re working with, and the needs and wants of the specific job they’re going to do with it. With advances in flue gas component detection, electronics miniaturization, and analyzer component reliability, there are many options on the market for HVAC technicians to choose from.

Most analyzers are handheld devices that work on either rechargeable Lithium or disposable alkaline batteries to power the internal pump and sample probe, so they can be used at the job site. The user interface (UI) should be easy to read and navigate with a backlit screen or a large, full-color touchscreen that presents a lot of information at once.

Most analyzers present oxygen and CO readings in ppm and %, respectively. Some stand out in the industry for having more advanced functions, such as data-logging and bluetooth communication. One example is UEi’s EcoOxygen, which uses its proprietary Electro Optic Sensor to directly measure O2 using light instead of using an O2 probe that requires calibration and replacement.
