Ventilation systems

For ventilation systems to provide an ideal working climate, they have to be optimally adjusted and maintained at all times. The compact measuring instruments from the testo Smart Probes range allow you to conveniently measure air flow velocities in ducts and at outlets by smartphone. The practical Smart Probes are always to hand for immediate use.

How testo Smart Probes offer support for your ventilation systems

  • Measurement of air velocity, volume flow and temperature with the testo 405i thermal anemometer

  • Simple configuration of the dimension and geometry of the duct cross-section for determining the volume flow

And this is how the testo Smart App helps you in this application:

  • Following intuitive input of the duct cross-section, the App calculates the volume flow completely automatically.
