Fits in any shirt pocket: With the testo 410i vane anemometer, you are well-equipped to measure air velocity and temperature at air outlets and ventilation grilles. Measuring and adjusting the volumetric flow rate is also a breeze. The testo 410i offers maximum flexibility and is ready for unplanned measurement requirements in your daily routine.

Measurement comfort thanks to the app: The testo 410i combines professional measurement technology from Testo with the efficient functions of an app. This turns your smartphone or tablet into a display for your measurement values on-site. You can view all measurement data through the testo Smart App and easily send the report as a PDF or Excel file via email.

With the app, configuring the volumetric flow measurement becomes very simple, especially since you can intuitively parameterize the outlet (dimension, geometry). Particularly useful: when balancing a ventilation system, volumetric flows from multiple outlets can be compared side by side. The temporal and pointwise averaging quickly provides insight into the average air velocity, for example, at a ventilation grille.

System requirements: iOS 11 or newer, Android 6.0 or newer, Bluetooth 4.0.
