testo 417 Rotating vane anemometer

The Testo 417 rotating vane anemometer has a 4-inch vane, allowing for precise readings of air velocity, CFM, and temperature on its easy-to-read display. By inputting duct measurements into the 417, volume flow calculations can automatically be displayed. With the capability of quickly switching between air velocity and temperature measurements, using the Testo 417 air flow meter is a breeze.
