Determining the volumetric air flow of a room ventilation system isn’t that easy. This is because the different flow velocities, turbulences, or wrong measuring position can affect the measuring values.

With the testo 417 vane anemometer with volume flow straightener you are therefore perfectly equipped. However, proper application is as important as the right instrument.

The tips and tricks in our new video will help you to achieve the correct results in future both quickly and easily:

• Measure more quickly at supply air outlets thanks to a 100 mm vane and testovent 417 funnel set

• Record the volume flow properly at exhaust air outlets with the testovent 417 funnel set

• Measure turbulent flows at swirl outlets accurately with measurement funnels and testovent 417 volume flow straightener
