Combustion analysis is crucial for the proper operation and control of any combustion process. Combustion occurs when fuels react with oxygen to produce heat. When combustion is harnessed to provide useable heat, the goal is to retrieve energy from the fuel in the most efficient manner possible. This means burning the fuel as completely as possible with the least amount of loss.
Bacharach is well-known manufacturer of HVAC equipment, including combustion analyzers.

Today 
I am reviewing the TPI 717 Combustion Flue Gas Analyzer series. The TPI 717 and TPI 717R are essentially the same device, but the TPI 717R uses a rechargeable Ni-MH battery, while the TPI 717 uses standard AA batteries. The TPI 717 series measures flue temperature, CO, and O2 and calculates efficiency, excess air, CO2, and CO/CO2 ratio.
