This year at PHEX Manchester, on the 4th & 5th October, we will be introducing the new testo 320 Flue Gas Analyser. Designed to provide the domestic engineer with all the functionality to provide a complete heating system diagnosis, the testo 320 Flue Gas Analyser has a colour graphic display, providing a unique user interface experience to allow simple access to measurement menus for flue gas analysis, draught measurement, pressure, ambient CO measurement, letby & tightness testing, and many more. Use the testo 320 to quickly determine and eliminate malfunctions, monitor legal limit values and spot checks in daily work on servicing heating systems.
The testo 320 Flue Gas Analyser comes as standard with bluetooth communication to android devices such as a smartphone or tablet device using the testo combustion App. This allows users to control the analyser remotely, view graphical data on set parameters, and also provide fast and efficient reports on measurements direct from site via email.
The 320 can also be equipped with optional probes to provide the abilty to carry out gas leak detection on pipework, and also if required measurement of ambient CO & CO2 values.
Also on the stand
Other technology we will have on display includes our award winning testo Smart Probes.
Smartphones and tablets make our day-to-day life easier in almost every situation, so why can’t this apply to contractors’ measurement tasks? That’s precisely what testo’s product developers asked themselves – and the result was the Smart Probes range.
The testo Smart Probes range makes measurement easier, more mobile and more productive than ever before
The eight pocket-sized professional measuring instruments, which can be connected to a smartphone or tablet via Bluetooth, are operated entirely via the free Smart Probes App. Each instrument has been designed for it’s own specific application, measuring temperature, humidity, pressure or air velocity. Competitively priced, testo Smart Probes are the ideal instruments for HVAC contractors with an enthusiasm for technology.
Come and see us at the show!
Visit testo on stand 29 at PHEX Manchester, Old Trafford (Manchester United FC) on the 4th & 5th October.
Come to the stand and speak to the testo sales team to find out about the testo 320 and the many other products that we can provide to heating system engineers, and get hands on with the instruments to see and feel the quality.

Testo Limited has pledged its support for Gas Safety Week (18-24 September 2017). The seventh annual Gas Safety Week will see organisations from across the UK work together, to encourage all gas consumers to make sure they have their gas appliances checked annually by a Gas Safe registered engineer and protect against the dangers of unsafe gas appliances, such as fires, leaks, explosions and carbon monoxide (CO) poisoning.
With 21 deaths and over 800 gas-related injuries in the last three years1, it’s crucial that people have their appliances checked each year to be assured they are working safely and efficiently. People should also Trust the Triangle and check that their engineer is Gas Safe registered. Anyone working on gas appliances while not being registered is working illegally.
Mike Murley, Marketing Director at Testo Limited commented, “As a leading manufacturer of gas safety instruments, Testo is proud to support Gas Safety Week. Testo instruments, such as flue gas analysers and gas leak detectors, are used by Gas Safe registered engineers to ensure that domestic boilers are operating safely and efficiently and to provide consumers with evidence of this”.

Stay Gas Safe at home this Gas Safety Week by following these top tips:
- Sign up to a free annual gas safety check reminder service at staygassafe.co.uk
- Be aware of the signs that an unsafe gas appliance may cause such as a lazy yellow flame instead of a crisp blue flame; soot or staining on or around the appliance; excess condensation in the room
- Know the symptoms of carbon monoxide (CO) poisoning. CO gas is known as the ‘silent killer’ as it has no smell, taste or colour. The symptoms of CO poisoning include headaches, dizziness, nausea, breathlessness, collapse and loss of consciousness, which can easily be mistaken for something else
- ‘Trust the Triangle’ and always ask to see an engineer’s Gas Safe ID card and check it to make sure the engineer is qualified to check or fit the appliance in question.

Install, inspect and service air conditioning and ventilation systems in ducts and at outlets
The correct and efficient adjustment of ventilation and air conditioning systems makes very high demands on measurement technology, due to various measurement locations and different flow velocities. Whether the precise determination of volume flow, quick spot measurements in ducts or the recording of turbulent flows at outlets: without suitable measuring instruments, it is impossible to ensure optimum indoor air quality in residential and non-residential buildings. Immediate effects of indoor air pollution often resemble those from a common cold or illness, making a potential issue even more difficult to detect. There are several illnesses that result from contaminated indoor air. Some of the more minor effects include irritated eyes, nose or skin as well as an increased likelihood of irritation of the eyes, coughing, headaches, dizziness, fatigue and nausea.
The most accurate measurement results can be achieved by measuring directly in a duct. However, since ventilation ducts are in practice frequently hidden or inaccessible, it is often necessary to resort to outlet measurements. In addition to this, turbulence in ducts and at outlets can often falsify measurements as well. These are just a few of the issues that engineers may encounter when carrying out precise flow velocity measurements.
Accurate and convenient measurement in ducts.
Ventilation and air conditioning systems are indispensable for indoor air quality; for them to function smoothly and efficiently, they must be tested regularly, and if necessary readjusted. If the air flows in ventilation ducts are smaller than intended, the removal of indoor loads (hot, cold and substance loads) can under certain circumstances not be guaranteed.
If the ventilation duct is accessible, duct measurement is the best solution. This is because air flows are measured most accurately directly in the duct. However, it must be considered that the flows in the duct are usually non-homogenous and turbulent. To obtain reliable results despite this, measurements should always be taken at several measuring points over the duct cross-section. In these grid measurements, a mean flow velocity is derived from the individual measurement values.
With the patented flow straighteners from Testo, even turbulent flows can be measured accurately.
The right ventilation measuring instruments support you in grid measurement just as reliably as in the automatic calculation of volume flow. Which instrument suits your application depends on the flow velocity range you wish to measure.
Precise measurement at outlets.
The quality of the indoor air depends crucially on whether the air input or output volume flows are optimally adjusted. For this reason, the measurement is taken directly at the outlet during adjustment work. However, inaccessible ventilation ducts also make measurements at outlets necessary. At swirl and plate outlets or ventilation grilles however, turbulence is created, which can falsify the measurement results and which are essential to consider.
To be able to measure these non-uniform flow profiles, it is essential that a funnel measuring instrument includes an integrated flow straightener that converts the turbulence into an almost uniform and easily measured air flow to guarantee the greatest level of accuracy, even in strong air turbulence.
Testo offers the optimum solution for every measurement task and measurement range: thermal probes, vane anemometers, differential pressure measuring instruments, funnel measuring instruments and multifunction measuring instruments. With the patented flow straighteners from Testo, even turbulent flows can be measured accurately. Testo’s free Apps make ventilation measurement also more convenient and less stressful than ever before.
