Testo 417, Rotating vane anemometer

With readings of up to 4,000 fpm, the Testo 417 rotating vane anemometer is ideal for collecting air velocity, CFM, and temperature measurements at supply and return grills. Having a larger vane, this air flow meter can cover a larger surface area, ensuring accurate measurements with each use. 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.-Air velocity, CFM, and temperature measurements-Multi-point and timed average calculations for in-duct readings-Bright backlit display provides easy viewing in any environment-“Hold” button freezes readings for easy recording
