Published on

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, – 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.

  1. 1. Committing to the future 2011Measurement Engineering for Air Conditioning and Ventilation
  2. 2. 2 Checking Indoor Air Quality using the new testo 435 multi-function meter testo 400, the reliable reference measuring instrument For a good climate Air conditioning and ventilation engineering is a complicated and pressure, lux, sound, CO2, volt and milliampere. Absolute assurance multifaceted field – You know that as well as we do. is supplied by Testo Calibration Certificates, regardless for which parameter. Testo has a pacesetter function in the calibration sector. Highly diverse tasks such as planning, initial operation, approval and service with different interfaces and high demands on energy How accurate are you? efficiency, hygiene and Indoor Air Quality all have to function in Measuring instruments have to measure accurately, stably and reliably harmony. over a period of years. These requirements are the basis of our product philosophy. An indication of how serious we are is made clear Technical requirements are high. Low energy consumption, high by the example of the development of our own, patented humidity operational safety, long-term availability, – at the same time, it must sensor. It took almost eight years before the sensor met our be possible to regulate air conditioning and ventilation in the different requirements in terms of precision and long-term stability, response rooms individually and in real time. time and temperature tolerance. It was then subjected to thorough testing lasting more than a year before it was finally approved for use Testo has the measurement engineering required. Complete solutions by our customers. But we were still not satisfied. Over a period of five for all parameters. Our many years of experience are reflected in our years, inter-laboratory tests were undertaken involving nine renowned practical and efficient measurement solutions. international testing institutes, such as the PTB in Berlin (National metrology institute), which documents the accuracy of the sensor Nobody offers more over this time in each of the testing institutes. It is impossible to find a comparable range of probes, optional probes or conventional probes, for all the parameters required in air conditioning: flow, humidity, temperature, pressure, absolute

Or how are draughts in offices assessed?If you need the answers to the above questions, just give us a call. lotWe will do our best to help you. 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. Mr. Schleeh, what developments do you see in air conditioningInter-laboratory tests engineering?Three precision probes were tested in extensive inter-laboratory testsat the PTB in Berlin, NIST in the USA, in the French National Institute In the EU, there is a strong trend towards air conditioning in rooms,CETIAT, the Italian national institute IMGC, the English national particularly in Southern European countries but also in Germany. Ininstitute NPL, the Spanish national institute INTA, at JQA in Japan, particular, split systems, decentralised systems for partial airKRISS in Korea, NRCCRM in Peking and in the Testo DAkkS conditioning in which an outside unit is combined with one or morecalibration laboratory. The results measured confirm a probe accuracy inside units, are on the increase. The technical development isof ±1 %RH as specified by Testo. clearly targeting at a high efficiency level using intelligent system and regulation concepts. What significance does measurement engineering have in your sector? 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. What keeps you loyal to 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. With the few defects 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.
