ASK THE EXPERT The best tools for the highest standards


When working in building analysis, every task is crucial to ensure quality. In order to fulfil each task to the highest standard, it is essential to have the best tools for the job


How do I ensure that air conditioning systems are working efficiently?


Most modern workplaces have high- performance ventilation and air conditioning systems, which require a great deal of energy. In order for them to be running at the most efficient level, these systems must be regularly and properly maintained. The good news? Testo have a range of tools that are perfect for the job! The testo 425 digital hot wire anemometer is ideal for work in ducts. Flow and temperature measurement plus volume flow calculation in the ventilation duct is now simple, fast and with precise results. The cable-connected telescopic probe can be extended up to 820mm, meaning you can work overhead or in large diameter ducts with ease. All relevant calculations, such as point averages and volume flow or time, are performed automatically by this compact and robust measuring instrument. For more information on the testo 425, visit https://www. testo.com/en-UK/testo-425/p/0563-0425 Working with air inlets and outlets? The testo 417 digital vane anemometer is the instrument for you, helping you efficiently regulate balanced residential ventilation. Adjustments for balanced residential ventilation or measurement at swirl outlets also becomes a simple task with the testo 417 kit including funnel and flow straightener. These can be easily attached to the vane, covering a wide range of outlet sizes and formats. For more information on the testo 417, go to https://www.testo.com/ en-UK/testo-417/p/0563-0417


Does a functioning a/c system mean that good indoor air quality is guaranteed?


For a pleasant indoor climate, ventilation and air conditioning units are indispensable. In order to ensure a good quality of air indoors, it is important to measure parameters of flow, air ducts, outlets and filters. There are also a number of additional factors that can affect this, such as the size of an indoor space, pollution from nearby combustion and the number of people using a room. However, the carbon dioxide concentration is one of the most important indicators of the quality if air indoors. To obtain crucial measurement of carbon dioxide in the air, suitable measurement equipment is a must. The testo 535 digital CO2 measuring instrument is your perfect partner in ensuring the quality of air indoors. This compact instrument allows you to carry out this important measurement easily and


efficiently. Thanks to the long-term stable infrared sensor technology, measured values are reproduceable and comparable even over long periods of time, which means it is ideal for recurring comparative measurements.

Are heating systems important for building analysis?


The function of a heating system is to raise the temperature of air being pumped into an indoor space to ensure a comfortable and desired level. Most heating systems generate heat either by using fuel or converting an energy source. These are especially used to counteract cold outdoor weather conditions and the energy source or fuel can vary from system to system. A properly functioning system will allow for an ideal level of indoor comfort for people occupying a space.


How can I check heating systems are working properly?


There are a number of different factors that go into a working heating system. When one of these factors goes wrong, it can be a struggle to find which. Whether it is a leak, high transfer resistance or something else causing an


anomaly, it is important to locate issues quickly in order to maintain an optimally running system. A worldwide staple for working with heating systems is a flue gas analyser. The long pipes that discharge exhaust gases are referred to as flue. To us a flue gas analyser, a probe is inserted into the flue of whichever heating system is being used. The gases flues eject will vary depending on the operations taking place in each property and have a wide range of compositions. Analysing flue gas is important for detecting the concentration of different gases, regulate burners and ensure the system is working to it’s optimal performance.

An effective method for visualising heat anomalies is by using a thermal imaging camera to visualise any heat anomalies. This is because it allows you to see any problem areas straight away without causing unnecessary destruction to property. Developed for service engineers, facility managers and building energy consultants, the testo 883 thermal imaging camera is a reliable partner when carrying out thermal measuring tasks. Detect thermal anomalies in installations and buildings as simply as pointing and clicking. For more information on the testo 883, go to https://www. testo.com/en-UK/testo-883/p/0560-8830


Will that make the building energy efficient?


Maintaining heating and ventilation systems is important when aiming to improve the efficiency of a building. A properly working system makes sure that air movement is sufficient and heat is remaining indoors. This will allow a good level of indoor air quality to be maintained throughout the building. In order to ensure efficiency across a building, preventative maintenance must be carried out.


What does it mean to carry out preventative maintenance?


Preventative maintenance refers to the act of proactively checking on potential risk and problem areas. It is a vital strategy for maintaining a good working order of a building’s critical assets. It requires inspections to be carried out regularly, with the possibility of selected repairs and services to the building dependant on results. Common problem areas include cold corners of rooms as they may lead to mould growth, routine maintenance on equipment and checking insulation for hot air escaping.
