The AOX2 Combustion Check Accessory measures percent oxygen (%O2) and flue temperature and calculates percent carbon dioxide (% CO₂). The AOX2 is an affordable alternative to full-function combustion analyzers. It's designed for techs who want to do everyday combustion testing and tuning, without paying for all of the costly extras found on combustion analyzers - extras they don't need or care about. The AOX2 allows you to easily calibrate combustion equipment such as boilers or furnaces to the manufacturer’s specified % CO₂, or % O2. Tuning the CO₂, O2 stack temperature and temperature rise to match the appliance manufacturer’s specifications will increase efficiency and help maximize performance and life expectancy of the equipment. Tuning typically involves adjusting the air/fuel ratio.
