The new SOX2 Combustion Check meter measures percent oxygen (%O2) and flue temperature and calculates percent carbon dioxide (%CO2) and percent excess air (%EA). The SOX2 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 SOX2 allows you to easily calibrate combustion equipment such as boilers or furnaces to the manufacturer's specified Excess Air %, CO2%, or O2%. Tuning the Excess Air, 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.
How Does it Work?
The SOX2 measures flue gas %O2 and temperature. From these measurements, it calculates and displays %CO2 and %EA. Most manufacturers include targets for these parameters on the data plate or in the technical specifications.
For example, while the heating appliance (furnace, boiler, heating stove, etc.) is in operation:
1. The technician taps into the flue and inserts the probe tip with the hi-temp thermocouple installed as directed in the SOX2 operator's manual.
2. He uses the hand pump to sample the flue gas until the measurements become stable.
3. He presses the H/MAX/MIN button to toggle between a real time reading, a held reading, the maximum reading, or the minimum reading for each test parameter.
4. He adjusts the system to match manufacturer's specifications.
