The TPI 717 Combustion Analyzer is a state of the art, easy to use analyzer designed not only to display and calculate the required readings from a flue but also to cover most of the other desirable parameters associated with appliance installation and maintenance.


Fast purge and the ability to perform fuel selection during start up enable tests to be performed quickly without requiring extra set-up time after initial startup. TPI analyzers also use the last selected fuel as the default setting. This feature prevents the need to perform fuel selection every time the analyzer is turned on.

  • Combustion Efficiency Analyzer: Measure O2, CO, and flue temperature. Calculate efficiency, excess air, CO2 & (CO/CO2) Ratio.
  • CO Analyzer: Measure carbon monoxide in ambient air.
  • Differential Manometer: +/- 150 mBar (0.01 mBar resolution). Great for tightness/let by or burner pressure testing.
  • Differential Thermometer: Dual input K-Type thermocouple thermometer measures differential temperatures. Ideal for measuring & recording flow & return temperatures.
  • Integrated Magnet for hands-free use; Push on fittings for fast and easy use

Frequently Asked Questions

Can I use my analyzer on Oil Fired Appliances?

Yes. Please ensure that the analyzer is set to the correct fuel and that the additional oil filter (A773) is fitted. It is also recommended to use a smoke pump before performing any analyzer test. NOTE: Do not use the A773 oil filter if an NO/NOx sensor is fitted

Can I use my analyzer to perform Tightness Tests?

Yes. All TPI Flue Gas Analyzer models have pressure which will allow all types of pressure testing to be performed; the 716 has in-built software which makes Tightness Testing even easier to perform.

Can I read Flow & Return Temperatures with a TPI Analyzer?

Yes. All TPI Flue Gas Analyzer models have Differential Temperature (Dual Inputs) which enables 2 temperatures to be taken at the same time and the difference calculated and displayed.
