Product Review

he AOX2 Combustion Check Accessory measures percent oxygen (-Percent O2) and flue temperature and calculates percent carbon dioxide (-Percent 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.
