Testo 400563 417N Large Rotating Vane Anemometer Kit with NIST Cert.
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, using the testo 417 RVA is a breeze.
With readings of up to 4,000 fpm and the attached large vane, the testo 417 rotating vane anemometer kit is ideal for collecting reliable measurements for air velocity, CFM, and temperature at both supply and return grills. The included soft carrying case ensures the air flow meter is protected against light drops and the elements.
