4 2 For a good climate Air conditioning and ventilation engineering is a complicated and multifaceted field You know that as well as we do. Highly diverse tasks such as planning, initial operation, approval and service with different interfaces and high demands on energy efficiency, hygiene and Indoor Air Quality all have to function in harmony. Technical requirements are high. Low energy consumption, high operational safety, long-term availability, no refrigerant losses at the same time, it must be possible to regulate air conditioning and ventilation in the different rooms individually and in real time. Testo has the measurement engineering required. Complete solutions for all parameters. Our many years of experience are reflected in our practical and efficient measurement solutions. Nobody offers more It is impossible to find a comparable range of probes for all the parameters required in air conditioning: flow, humidity, temperature, lux, sound, CO2, volt and milliampere. Absolute assurance is supplied by the Testo Calibration Certificates, regardless for which parameter. Testo has a pacesetter function in the calibration sector. How accurate are you? Measuring instruments have to measure accurately, stably and reliably over a period of years. These requirements are the basis of our product philosophy. An indication of how serious we are is made clear by the example of the development or our own, patented humidity sensor. It took eight years until the sensor met our requirements with respect to precision and long-term stability, response time and temperature tolerance. It was then subjected to thorough testing lasting more than a year before it was finally approved for use by our customers. But we were still not satisfied. Over a period of five years, inter-laboratory tests were undertaken involving nine renowned international testing institutes, such as the PTB in Berlin (National metrology institute), which documents the accuracy of the sensor over this time in each of the testing institutes.

5 3 Learning changes What was the difference again between standard and working volume flow? Or how are draughts in offices assessed? If you need the answers to the above questions, just give us a call. We will do our best to help you. We owe Testo a lot Wolfgang Schleeh, Head of Commissioning at M+W Zander Facility Engineering GmbH Mr. Schleeh and his team are not only loyal Testo customers, they also attend seminars on air conditioning and ventilation engineering at Testo on a regular basis. Inter-laboratory tests Three precision probes were tested in extensive inter-laboratory tests at the PTB in Berlin, NIST in the USA, in the French National Institute CETIAT, the Italian national institute IMGC, the English national institute NPL, the Spanish national institute INTA, at JQA in Japan, KRISS in Korea, NRCCRM in Peking and in the Testo DKD calibration laboratory. The results measured confirm the probe accuracy of ±1 %RH as specified by Testo. Mr. Schleeh, what developlments do you see in air conditioning engineering? In the EU, there is a strong trend towards air conditioning in rooms, particularly in Southern European countries but also in Germany. In particular, split systems, decentralised systems for partial air conditioning in which an outside unit is combined with one or more inside units, are on the increase. The technical development is clearly targeting at a high efficiency level using intelligent system and regulation concepts. What significance does measurement engineering have in your branch? In order to be able to ideally adjust air conditioning and ventilation systems, we have to know numerous parameters and adjust them to each other. Without the proper measuring instruments and the know-how as to how to measure, it would simply be impossible to measure. What do you associate with Testo? The right instrument for every measurement job in air conditioning and ventilation engineering. I do not know any other company with such a comparable complete and well thought-through range of products for our sector. You could nearly believe that the Testo developers watch us everyday when we are measuring. For example, the SoftCase protection case with magnetic holder so that I can attach my meter to the system and have my hands free to guide the probe and make adjustments. Service is also first-class. In the case of the few defects which we experienced over the years, we always received help straightaway. When we had to send in an instrument, a replacement instrument was immediately made available to us. In your sector you could be referred to as an old hat, why are you still attending seminars at Testo? Even old hats have to keep up-to-date. I have to pay attention to new developments in measurement engineering and new technical rules and legal stipulations about which I want to be informed. I always choose the aspects which I consider important. The same applies to my colleagues What would you write for Testo in the register? Good instruments, good service, a lot of know-how. We owe Testo a lot.

11 9 For professional assessors The testo 400 with the VAC module is currently the only measurement system in the world with which a fast and objective assessment of the functionality of a VAC system is possible without the need for additional manual calculations. Of course, the measurement stipulations are based on the EN Standard as well as the Ashrae Standard USA. The measurement technician always has one hand free. Site data, such as location name, measurement coordinates, duct area, offset factor etc. is read automatically into the measuring instrument via the barcode reader. The measurement data saved in testo 400 is uploaded to the PC at the touch of a button. Timeconsuming manual written work will now be a thing of the past, the required calculations are completed automatically by testo 400. Measurement results are documented in an EN standardised layout.

The comfort probe, which is independent of direction, has been designed especially to assess draughts. The mean air velocity alone is not sufficient to assess the effect on humans. Temporal fluctuations in ambient air velocity is of particular interest. One measure of this is the degree of turbulence required in the corresponding standards and guidelines. This is calculated automatically by testo 400.

18 16 Humidity and Temperature Measurement Professional and Efficient How many degrees are there really? Wolfgang Schwörer, Head of Competence Center VAC How can you be sure that your analyser measures exactly what it should be measuring? Our certified DKD laboratories are unbeatable in their accuracy and give the values for all Testo measuring instruments - That s what true measurement efficiency is all about. The following can be connected: Temperature probe Humidity probe with 2 year guaranteed long-term stability The competence of our engineers is held in high esteem by expert groups and committees in Berlin and Brussels where they are involved in the developments of future guidelines in their capacity as respresentatives of industry. Easy to determine dewpoint difference thanks to display of surface and dewpoint temperature A comprehensive exchange of knowledge and experience with official measurement institutes around the world (e.g. DKD) ensures that your Testo measuring instrument can hold up to any comparison. Indeed, these efforts do have an objective: whoever uses Testo measurement engineering, can be assured that he is using the industrial standard. Data documentation printed on site on printer (optional) Of further benefit to you: We know today about the guidelines and test specifications we will be faced with in the future. TopSafe, saves instrument from dirt and impact (optional)
