A competition prize worth £269, a NEW product launch, and More! Find out what Testo has on offer at the HVAC & Refrigeration Show!

Testo have led the ‘smart’ revolution in giving HVAC/R service engineers a wide range of test instruments with Bluetooth connectivity to smartphones or tablet devices, enabling them to work smarter and to gain benefits such as on-site reporting and improved documentation of test results.

Now you have the chance to win a free testo 550 digital manifold worth £269 at the HVAC/R show just by heading over to the Testo stand B39 and putting your details into the draw – the winner will be announced just after the show closes on the 25th January.

The Testo 550 is a 2-port manifold allowing the engineer to get fast and accurate measurements of highside and lowside pressures as well as condensing and evaporation temperatures. The other added bonus of moving to digital manifolds is that the user also gets real time display of superheat and subcooling values as well.

An often overlooked additional benefit of Testo digital manifold’s is that they allow the user to easily update the device for new refrigerants that are introduced via a smartphone or tablet and the Bluetooth app. Currently the testo 550 supports over 60 different refrigerants. Also, the manifold incorporates a temperature compensated leak test function that allows engineers to fully test a system and shows the start/end system pressure and the time of the test.

The free App to support the manifolds also allows on-site documentation of test results with the ability to provide clear and concise reports for clients.

Introducing the NEW testo 440

At the HVAC & Refrigeration show we will be launching a new air velocity & IAQ measuring instrument to the public. The testo 440 combines a compact handheld measuring instrument with user-friendly measurement menus and wide selection of wireless probes – for the versatile and convenient measurement of all air conditioning, ventilation, and indoor air quality parameters.

We will have the new testo 440 and a selection of probes on display at the show. Visit our stand B39 to get hands on with the new product and find out more about its functions and applications.

Smart Probes Refrigeration Set

From the award winning Testo ‘Smart Probes’ range comes the ‘Refrigeration Set’ which effectively turns your smartphone into a digital refrigeration manifold, with clear display of both highside/lowside pressure and temperatures as well as direct readings of superheat and subcooling values – all without requiring any use of traditional temperature/pressure lookup tables, and giving faster, more accurate measurements of a refrigeration systems performance.

 

Digital Manifolds

For users who prefer a more traditional ‘digital’ manifold type product the testo 550 and testo 557 units provide either a 2-port (testo 550) or 4-port (testo 557) option. Again, these products have Bluetooth communication to the free to download ‘Refrigeration App’ and this allows engineers to view the measurements either directly on the manifold, or remotely up to 10m away on their smartphone or tablet.

With many existing refrigerants having major increases in costs it is more important than ever to make sure that systems are fully pressure tight before filling to ensure no loss.  A key function with the Testo digital manifolds is the ability to perform a temperature compensated tightness test following any work to repair a leak to a system, and this is one area where traditional ‘analogue’ gauge sets can often perform poorly.

Finally, with all the changes going on as part of the drive to refrigerants with lower GWP it is essential that engineers can update any manifolds to suit. Again, with traditional analogue type units this normally means extra cost in purchasing new gauges, however with the Testo digital manifolds any update to the refrigerants tables available is simply done via the Bluetooth connection to the free ‘Refrigeration App, ensuring that refrigeration and AC engineers are always in touch with technology changes.

All outlets – All flow velocities – One expert.

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.
