  3. Thermal anemometer for airspeed

Thermal anemometer

Airspeed is a value which may be of importance in many areas. The focus here is above all on values in a ventilation duct, but it may also make sense to carry out an airspeed measurement inside rooms. The use of an anemometer is helpful here.

Measuring airspeed – thermal anemometer in use

The anemometer is also referred to as a wind speed meter. However, it is not just a case of using it to measure wind speed, it can also record the volume flow. Many anemometers therefore have an integrated flow meter. The air flow velocity and the volume flow inside rooms have an influence on the indoor air quality. Regular measurement is all the more important, because influencing factors are involved here which are in most cases impossible to detect at first sight.

If you want to buy a thermal anemometer, the following features are particularly useful:

  • timed mean value calculation

  • combination of temperature, flow and volume flow measurement

  • hold functions

Measuring wind speed – the influence of air flows on indoor air quality

The measurement of wind speed is not just an interesting factor in the outdoors in terms of finding out more about the ambient conditions. The wind speed meter is now also more and more frequently used indoors. In this context, it is referred to as a thermal anemometer.

The vane anemometer is very commonly used in this area. This instrument has a probe head which can be employed to measure the airspeed and volume flow. Temperatures of up to 140°C can occur with a model that is suitable for the measurement of high temperatures and the anemometer will continue to carry out accurate measurements.

Wind measurement is for instance carried out with an anemometer inside rooms when there are uncertainties about the air flows and air temperature. The reasons for this may be structural defects or also leaky windows. In some cases, the flows are so small that they cannot always be identified immediately. However, they can be quickly detected by using an instrument as sensitive as the anemometer.

A thermal anemometer has the following advantages:

  • wind measurement indoors as well

  • volume flow measurement possible

  • measurement of air temperature in some cases

  • analysis and image documentation in some cases

Thermo anemometer with smartphone connection

Nowadays, it may be particularly helpful to use an anemometer which also has a smartphone connection. This makes analysis and reception of the values considerably easier. You can order a thermo anemometer with smartphone operation from Testo.

The model is able to measure volume flows and temperatures, as well as airspeed. The measuring values themselves are then sent to an App. This enables you to obtain the values directly and analyze them, as well as comparing them to other measurements.

A flow meter or a wind speed meter that has a connection to a smartphone also ensures that it is easier to carry out measurements in ventilation ducts in particular. The Apps which are available for the instruments are also very easy to use and have an intuitive user interface.

Buying a wind meter from Testo

If you want to buy a wind speed meter, you will find a selection of different models at Testo. Classic anemometers for the measurement of air flows are also included, along with pure flow meters or combination instruments, which can also be used to measure temperatures.
