While CO is important, it is only one of the measurements a combustion analyzer can make. If you are just using your combustion analyzer as a CO meter, you are doing a disservice to yourself and your customers. The combustion analyzer can be used for so much more. Most analyzers incorporate digital manometers, dual thermometers, and CO oxygen (O2) sensors. They can be used for everything from checking gas pressure to building depressurization, to pressure drops across filters and coils. They can measure stack temperature and temperature rise across the furnace.
The O2 and CO sensors verify efficiency and are great tools for checking heat exchangers, combustion air, and ventilation. With features like wireless printers and USB connections to your PC, there is an analyzer to fit everyone's needs.
