Precise measurement at outlets with Testo measuring instruments
Testo measurement technology provides reliable results even at swirl 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.
In order to be able to measure these non-uniform flow profiles, it is essential that a funnel measuring instrument with a flow straightener is used. Patented volume flow straighteners from Testo guarantee the greatest level of accuracy, even in strong air turbulence.
Highest accuracy even in turbulence
