  • Combustion Efficiency Analyser: Measure O2, CO, and flue temperature. Calculate efficiency, excess air, CO2 & (CO/CO2) Ratio.
  • CO Analyser: 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.
  • Six Year Warranty

All of the features of the 709R plus:

  • Timed Let/By & Tightness Test
  • Timed CO Build-Up Room Test
  • Integrated Magnet
  • Calibration Due Countdown on switch on
  • Serial Number on Print-Outs
  • Next Calibration Due Date on Print-Outs


The TPI 717R conforms to EN50379 and is suitable for engineers working with BS7967, the usage standard.

Serial Number & Next Cal Due Date are printed at the bottom of each print-out ensuring that you always know your readings have been taken with the correct in-calibration flue gas analyser giving you complete peace of mind.

HHIC: The Heating & Hotwater Industry Council made a recommendation that from April 2013 that the CO level & CO/CO2 (Ratio) reading in a flue is recorded when a boiler is commissioned and that this practise become mandatory from April 2014. Please click here for further details.

The recording of the CO level and Ratio reading will become a mandatory part of completing the Benchmark Form.

Combustion Performance Analysis (CPA1): From April 2012 it has been compulsory for all engineers to acquire CPA1 Assessment to prove their competency in using a Flue Gas Analyser. Please click here for complete details.
