Description of the Testo 410i Vane Anemometer • Compact professional measuring device from the Testo Smart Probes series for use with smartphones or tablets. Measures air velocity, volumetric flow, and temperature. Simple parameterization of the outlet for volumetric flow measurement (dimension and geometry). Displays the volumetric flow of multiple outlets for system balancing. Measurement data analysis and transmission via the Testo Smart Probes app. Space-saving and easy to transport. The compact Testo 410i vane anemometer is suitable, in combination with a smartphone or tablet, for measuring air velocity, volumetric flow, and temperature at the air outlet, as well as for balancing the volumetric flow of a ventilation system. Users can conveniently read their measurements, easily and quickly configure volumetric flow measurements, and reliably determine temporal and point averages through the Testo Smart Probes app installed on their device. Particularly practical for balancing a ventilation system.
