709R Kit 1: All Standard Accessories and includes:
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.

Analyser Frequently Asked Questions
Can I use my analyser on Oil Fired Appliances?
Yes. Please ensure that the analyser 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 analyser test. NOTE: Do not use the A773 oil filter if an NO/NOx sensor is fitted
Can I use my analyser to perform Tightness Tests?
Yes. All TPI Flue Gas Analyser 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 Analyser?
Yes. All TPI Flue Gas Analyser models have Differential Temperature (Dual Inputs) which enables 2 temperatures to be taken at the same time and the difference calculated and displayed.
