Description

Overview

The Testo 417 rotating vane anemometer has a 4-inch (100 mm) vane, allowing for precise readings of air velocity, volume flow (CFM) and temperature on its easy-to-read display. By inputting the duct measurements, volume flow calculations are displayed automatically, so you get representative results across an outlet quickly and reliably.

With the ability to switch instantly between air velocity and temperature measurement, the testo 417 is straightforward to use in the field. Its large integrated vane averages the airflow across an air outlet, and the instrument works with optional funnels for fast volume flow measurement at supply and extract grilles.
