With a large, easy-to-read, backlit display, simple to navigate operating system at a Low Starting Price of JUST £360.00 with Fixed Price Annual Servicing at £85.00, it really is the most cost efficient FGA on the market.

The standard kit comes complete with the 709R in a protective rubber boot, temperature sampling probe c/w external large water trap and unique in-lid water trap (as used by British Gas), soft carry case with shoulder strap, re chargeable battery pack & charger, pressure adaptors, ambient air probe, spare particle filter and instruction manual.


The TPI 709R 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.
